●Description of Block(s)

The BZ6Axx06GM are a synchronous step-down DC/DC converter that achieves fast transient response from light load to

heavy load by hysteretic PWM control system and current constant PFM control system.

○PWM control

BZ6Axx06GM operates by hysteretic PWM control. This scheme ensures fast switching, high efficiency, and fast transient

response.

When the output voltage is below the VREF voltage, the error comparator output is low to high and turning on P-channel

MOSFET until above the VREF voltage and minimum on time.

○PFM control

At light load the regulator and MODE=low, the regulator operates with reduced switching frequency and improves the

efficiency. During PFM operation, the output voltage slightly

higher than typical output voltage.

●Description of operations

1) Shutdown

If the EN input pin set to low (<0.4V), all circuit are shut down and the regulator is standby mode.

Do not leave the EN pin floating.

2) Soft start function

The regulator has a soft start circuit that reduces in-rush current at start-up. Typical start up times with a 4.7uF output

capacitor is 120usec.

3) Current limit

The BZ6Axx06GM has a current limit circuit that protects itself and external components during overload condition.

4) Under Voltage Lock Out (UVLO)

The BZ6Axx06GM has a Under Voltage Lock Out circuit that turn off device when VIN>2.05V(typ.)

5) FORCED PWM MODE

Setting MODE pin high (>1.4V) places the regulator in forced PWM.This control provides noise reduction and output

stability.

Do not leave the MODE pin floating.

6) TSD

The BZ6Axx06GM has a thermal shutdown feature to protect the device if the junction temperature exceeds 150℃.In

thermal shutdown, the DRIVER is disabled.

This circuit is only to cut off the IC from thermal runaway, and has not been design to protect or guarantee the IC. Therefore,

the user should not plan to activate this circuit with continued operation in mind.

●Caution of use

1) Absolute maximum ratings

An excess in the absolute maximum rating, such as supply voltage, temperature range of operating conditions, etc., can

break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any

over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as

fuses.

2) GND voltage

The potential of GND pin must be minimum potential in all condition. As an exception, the circuit design allows voltages

up to -0.3 V to be applied to the IC pin.

3) Thermal design

Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.

4) Inter-pin shorts and mounting errors

Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any

connection error or if pins are shorted together.

5) Actions in strong electromagnetic field

Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to

malfunction.

6) Mutual impedance

Power supply and ground wiring should reflect consideration of the need to lower mutual impedance and minimize ripple as

much as possible (by making wiring as short and thick as possible or rejecting ripple by incorporating inductance and

capacitance).

7) Thermal shutdown Circuit (TSD Circuit)

This model IC has a built-in TSD circuit. This circuit is only to cut off the IC from thermal runaway, and has not been design

to protect or guarantee the IC. Therefore, the user should not plan to activate this circuit with continued operation in mind.

8) Regarding input pin of the IC

This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated.

P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic diode

or transistor. For example, as shown in the figures below, the relation between each potential is as follows:

When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.

When GND > Pin B, the P-N junction operates as a parasitic transistor.

Parasitic diodes can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual

interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes operate,

such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used.
