AC/DC Drivers

PWM Control type

DC/DC converter IC

BM1P061FJ / BM1P062FJ / BM1P101FJ / BM1P102FJ

●General

The PWM type DC/DC converter (BM1Pxxx) for

AC/DC provides an optimum system for all products

that include an electrical outlet.

BM1Pxxx supports both isolated and non-isolated

devices, enabling simpler design of various types of

low-power electrical converters.

BM1Pxxx built in a HV starter circuit that tolerates

650V, it contributes to low-power consumption.

With switching MOSFET and current detection

resistors as external devices, a higher degree of

design freedom is achieved. Switching frequency

adopts fixed system. Since current mode control is

utilized, current is restricted in each cycle and

excellent performance is demonstrated in bandwidth

and transient response.

At light load, the switching frequency is reduced and

high efficiency is achieved.

A frequency hopping function is also on chip, which

contributes to low EMI.

BM1Pxxx also has built-in function such as soft start,

burst mode, over current limiter per cycle, VCC over

voltage protection and over load protection.

A: Input voltage VH is applied

B: This IC starts operating, when VCC pin voltage rises VCC > VUVLO1 (Typ=13.5 V).

Switching function starts when other protection functions are judged as normal.

Then the VCC pin voltage drop because of consumption current of VCC pin. In the case of VCC < VCHG1 (Typ=8.7V),

the starting circuit operates and changes the VCC pin. The charging continue until the VCC become less than VCHG1

(Typ=13.0V).

C: With the soft start function, the value of CS pin has to be restricted to prevent any excessive rise in voltage or

current.

D: When the switching operation starts, VOUT rises.

It is necessary that the output voltage is be set to be rated voltage until TFOLP2 (Typ=32ms) after starting switching.

E: At the light load condition, the burst operation starts in order to restrain power consumption.

F: The FB pin becomes more than VFOLP1A because the output voltage lowers at over load operation.

G: When FB pin voltage keeps more than VFOLP1A for TFOLP (Typ=64ms), the overload protection function is triggered and

switching stops. If the FB pin voltage becomes less than VFOLP1B, the IC’s internal timer is reset.

H : If the VCC voltage drops to VCHG1 (Typ=8.7V) or below, the starting circuit operates and VCC starts to charge.

I: If the VCC voltage raises to VCHG2 (Typ=13.0V) or above, the charging by the starting circuits stops.

(3) VCC pin protection function

BM1Pxxx has built-in VCCUVLO (Under Voltage Lock Out), VCC OVP (Over Voltage Protection) and VCC charge

function which operates in case of dropping the VCC voltage.

VCC UVLO and VCC OVP functions are the functions that prevent MOSFET for switching from destroying when the VCC

voltage drops or rises. VCC charge function stabilizes the secondary output voltage to be charged from the high voltage line

by start circuit at dropping the VCC voltage.

(3-1) VCC UVLO ／ VCC OVP function

VCCUVLO is auto recovery comparator that has the voltage hysteresis. BM1Pxx1 series has auto recovery type

VCCOVP. BM1Pxx2 series has latch type VCCOVP. It is necessary that VCC is less than VLATCH (Typ=7.7V) to reset the

latch after detecting latch operation by VCC OVP. Refer to the operation figure-8.

This function has a built-in mask time TLATCH（typ=100us）. This detects it if the condition that VCC pin is more than

VOVP1 (Typ=27.5V) continues for TLATCH (Typ=100us). By this function, it masks the surge occurs at the pins.

（3-2）VCC Charge function

The VCC charge function operates once the VCC become more than VUVLO1 and the DC/DC operation starts then the

VCC pin voltage drops to less than VCHG1. At that time, the VCC pin is charged from the VH pin. By this operation, BM1Pxxx

doesn’t occur to start failure.

(4) DCDC driver (PWM comparator, frequency hopping, slope compensation, OSC, burst)

BM1Pxxx performs a current mode PWM control. An internal oscillator fixes switching frequency. BM1Pxxx is

integrated the hopping function of the switching frequency which changes the switching frequency to fluctuate as

shown in Figure 10. The fluctuation cycle is 125 Hz typ.

Figure 10-1. hopping function (BM1P06x series) Figure 10-2. hopping function (BM1P10x series)

Max duty cycle is fixed as 75% (Typ) and MIN pulse width is fixed as 400 ns (Typ).

With the current mode control, when the duty cycle exceeds 50%, sub harmonic oscillation may occur. As a

countermeasure to this, BM1Pxxx has a built-in slope compensation circuits.

BM1Pxxx has a built-in the burst mode circuit and the frequency reduction circuit to achieve low power consumption, at

a light load.

The FB pin is pull up by RFB (Typ=30 kΩ). The FB pin voltage is changed by secondary output voltage (secondary load

power). By monitoring the FB pin voltage, the burst mode operation and the frequency detection is operated.

Figure 11 shows the FB voltage, the switching frequency and the DC/DC operation

・mode1: the burst operation

・mode2: the frequency reduction operation. (reduce the max frequency)

・mode3: the fixed frequency operation.(operate at the max frequency)

・mode4: the over load operation.(detect the over load state and stop the pulse operation)

(5) Over Current limiter

BM1Pxxx has a built-in the over current limiter per cycle. If the CS pin is exceeds a certain voltage, the switching is

stopped. It also has built-in the AC voltage compensation function. This is the function which compensates a

dependence of over current limiter value by AC voltage increasing over current limiter levels with time.

Shown in figure-12, 13, 14.

Figure 12. No AC voltage compensation function Figure 13.buit-in AC compensation voltage

The primary peak current is decided as the formula below.

The primary peak current: Ipeak = Vcs/Rs + Vdc/Lp*Tdelay

Vcs ：the over current limiter voltage

Rs ：the current detection resistance

Vdc ：the input DC voltage

Lp ：the Primary inductance

Tdelay：the delay time after the detection of the over current limiter

Figure 14. Over current limiter voltage

（6）L.E.B period

When the driver MOSFET is turned ON, a surge current occurs at capacitor components and the drive current. Therefore,

because of rising the CS pin voltage temporarily, the detection errors may occur in the over current limiter circuit. To prevent

this detection errors, this IC has a internal L.E.B function (Leading Edge Blanking function) that masks CS voltage for 250n

sec after the OUT pin switches from Low to High.

This L.E.B function reduces CS pin noise filter for the noise that occurs when the OUT pin switches from low to high.

(7) CS pin (3pin) open protection

If the CS pin becomes OPEN, the IC may be damaged because of excessive heat by noises. To prevent this damage,

BM1Pxxx has a built-in the OPEN protection circuit（auto recovery protection）.

(8) Output over load protection function （FB OLP Comparator）

The output overload protection is the function that monitors the secondary output load status at the FB pin and stops a

switching when an overload occurs.

At an overload condition, the output voltage is dropped and the current can’t flow at the photo coupler, so the FB pin

voltage is rised. If the condition

When the status that the FB pin voltage is more than VFOLP1A (Typ=2.8V) continues for TFOLP (Typ=64ms), it is judged

as an overload and stops switching.

If the FB voltage drops from VFOLP1A (Typ=2.8V) to VFOLP1B (Typ=2.6V) within TFOLP (Typ=64ms), the time of over load

protection is reset. The IC operates switching during TFOLP (Typ=64ms).

At start-up, so the FB voltage is pulled up to the IC’s internal voltage that the operation starts from VFOLP1A (Typ=2.8V)

or above. Therefore, at startup the FB voltage must be set to V FOLP1B (2.6 Vtyp) or below during T FOLP2 (32 ms typ),

and the secondary output voltage’s start time must be set within T FOLP2 (32 ms typ) following startup of the IC.

Recovery that once FBOLP is detected is after T OLPST (Typ=512ms).

Figure 15. Over load protection (Auto recovery)

A: The FBOLP comparator detects over load because the FB voltage is more than VFOLP1A.

B: If the states of A continues for TFOLP2 (Typ=32ms), it is judged as an overload and stops switching.

C: After the switching stops for the over load protection function, if the VCC pin voltage drops and the VCC pin voltage

become less than VCHG and the VCC charge function operates so the VCC pin voltage rises.

D: VCC charge function stops when VCC pin voltage becomes more than VCHG2.

E: If it is passed TOLPST （typ =512ms） from B point, switching function starts on soft start.

F: If the over load condition lasts, the condition that the FB pin voltage is more than VFOLP1A, too. And if it passed TFOLP

(Typ=64ms), the switching is stopped.

G: While the switching stops, if VCC pin voltage drops to VCHG1 or below, VCC charge function operates and VCC pin

voltage rises.

H: If VCC pin voltage exceeds VCHG2 by the VCC charge function, VCC charge function operation stops

(9) OUT Pin Voltage clamper

BM1Pxxx has a gate clamper function. It set the OUT pin high voltage to VOUTH（Typ=12.5V）.

It prevents MOSFET gate form damage of VCC pin (6pin) voltage. (Shown in Figure16)

Figure 16. OUT pin （5pin） Block Diagram

(10) ACMONI Function

Brownout function is built inside BM1PXXX. Brownout function means that DC/DC action will stop when input AC

voltage is low. Application example is shown in Figure 17. Input voltage is divided by resistance and is input into

ACMONI terminal. If the voltage of ACMONI terminal exceeds VACMONI1 (Typ=1.0V), the circuit detects normal status

and start to execute DC/DC action. After DC/DC action and voltage of ACMONI terminal is lower than VACMONI2

(Typ=0.7V), TACMONI (Typ=256ms) later, DC/DC action becomes OFF.

Figure 17. Application circuit

* If brownout function is not used, please set voltage value within the range of VACMONI(1.0Vtyp)～5.0V.

● Use-related cautions

(1) Absolute maximum ratings

Damage may occur if the absolute maximum ratings such as for applied voltage or operating temperature range are

exceeded, and since the type of damage (short, open circuit, etc.) cannot be determined, in cases where a particular

mode that may exceed the absolute maximum ratings is considered, use of a physical safety measure such as a

fuse should be investigated.

(2) Power supply and ground lines

In the board pattern design, power supply and ground lines should be routed so as to achieve low impedance. If there

are multiple power supply and ground lines, be careful with regard to interference caused by common impedance in

the routing pattern. With regard to ground lines in particular, be careful regarding the separation of large current routes

and small signal routes, including the external circuits. Also, with regard to all of the LSI’s power supply pins, in

addition to inserting capacitors between the power supply and ground pins, when using capacitors there can be

problems such as capacitance losses at low temperature, so check thoroughly as to whether there are any problems

with the characteristics of the capacitor to be used before determining constants.

(3) Ground potential

The ground pin’s potential should be set to the minimum potential in relation to the operation mode.

(4) Pin shorting and attachment errors

When attaching ICs to the set board, be careful to avoid errors in the IC’s orientation or position. If such attachment

errors occur, the IC may become damaged. Also, damage may occur if foreign matter gets between pins, between a pin

and a power supply line, or between ground lines.

(5) Operation in strong magnetic fields

Note with caution that these products may become damaged when used in a strong magnetic field.

(6) Input pins

In IC structures, parasitic elements are inevitably formed according to the relation to potential. When parasitic

elements are active, they can interfere with circuit operations, can cause operation faults, and can even result in damage.

Accordingly, be careful to avoid use methods that enable parasitic elements to become active, such as when a voltage

that is lower than the ground voltage is applied to an input pin. Also, do not apply voltage to an input pin when there is no

power supply voltage being applied to the IC. In fact, even if a power supply voltage is being applied, the voltage applied

to each input pin should be either below the power supply voltage or within the guaranteed values in the electrical

characteristics.

(7) External capacitors

When a ceramic capacitor is used as an external capacitor, consider possible reduction to below the nominal

capacitance due to current bias and capacitance fluctuation due to temperature and the like before determining

constants.

(8) Thermal design

The thermal design should fully consider allowable dissipation (Pd) under actual use conditions.

Also, use these products within ranges that do not put output Tr beyond the rated voltage and ASO.

(9) Rush current

In a CMOS IC, momentary rush current may flow if the internal logic is undefined when the power supply is turned ON,

so caution is needed with regard to the power supply coupling capacitance, the width of power supply and GND pattern

wires, and how they are laid out.

(10) Handling of test pins and unused pins

Test pins and unused pins should be handled so as not to cause problems in actual use conditions, according to the

descriptions in the function manual, application notes, etc. Contact us regarding pins that are not described.

(11) Document contents

Documents such as application notes are design documents used when designing applications, and as such their

contents are not guaranteed. Before finalizing an application, perform a thorough study and evaluation, including for

external parts.
