DESCRIPTION
The Si9145 switchmode controller IC is ideally suited for high
efficiency dc/dc converters in low input voltage systems.
Operation is guaranteed down to 2.7 V, with a minimum
start-up voltage of 3.0 V making the Si9145 ideal for use with
NiCd, NMH, and lithium ion battery packs. A mode select pin
allows the output driver polarity to be programmed allowing the
device to function as a step-up or step-down converter.
Features include a precision bandgap reference, a wide
bandwidth error amplifier, a 2-MHz oscillator, an input voltage
monitor with standby mode and a 200-mA output driver.
Supply current in normal operation is typically 1.1 mA and
250 mA in standby mode.
The Si9145 implements conventional voltage mode control.
The maximum duty cycle in boost mode can be limited by
voltage on DMAX/SS pin. Frequency can be externally
programmed by selection of ROSC and COSC.
The Si9145 is available in both standard and lead (Pb)-free
16-pin SOIC and TSSOP packages and is specified over the
industrial temperature range (−25_C to 85_C).

PIN DESCRIPTION
Pin 1: VDD
The positive power supply for all functional blocks except
output driver. A bypass capacitor of 0.1 mF (minimum) is
recommended.
Pin 2: MODE SELECT
This pin is used to enable maximum duty cycle limit and set
output polarity of controller. When connected to VDD, the
maximum duty cycle function is controlled by the DMAX/SS pin.
The maximum duty cycle limit is usually used for forward,
flyback, and boost converters. The output polarity is high when
the PWM circuitry requires the external device to be turned on.
When connected to GND, the maximum duty cycle is not
limited (usually for buck converters driving a p-channel MOS).
The output polarity is low when the PWM circuitry requires the
external PMOS to be turned on.
Pin 3: DMAX/SS
DMAX/SS pin controls the maximum duty cycle achievable by
the PWM circuitry when the MODE SELECT = VDD.
When DMAX/SS is at less than 1.0 V (typical) the OUTPUT is
held low (0% duty cycle). When DMAX/SS is at more than 1.5 V
(typical), the PWM circuitry can achieve 100% duty cycle. With
voltage at DMAX/SS between 1.0 V and 1.5 V, the maximum
duty cycle is proportionally limited to this voltage.
The addition of external components can implement a soft
start function.
Pin 4: COMP
This pin is the output of the error amplifier. A compensation
network is connected from this pin to the FB pin to stabilize the
system. This pin drives one input of the internal pulse width
modulation comparator.
Pin 5: FB
The inverting input of the error amplifier. External resistors are
connected to this pin to set the regulated output voltage. The
compensation network is also connected to this pin.
Pin 6: NI
The non-inverting input of the error amplifier. In normal
operation it is externally connected to the VREF pin.
Pin 7: VREF
This pin supplies 1.5 V trimmed to "1.5%. The reference
voltage is generated by a band-gap reference.
Pin 8: GND
Negative return for VDD.

Pin 9: ROSC
This pin is the equivalent of a 1.0-V voltage source derived
from the on-chip VREF . When a low T.C. resistor is externally
connected from this pin to GND, a temperature independent
current is generated internally. This current is used as the
charging current source connected to the COSC pin. The
current is internally multiplied by 2 and is used as the
discharging current source connected to the COSC pin.
Therefore, the external resistor is one of the factors that
determine the oscillator frequency.
Pin 10: COSC
An external capacitor is connected to this pin to set the
oscillator frequency. Internal current sources alternately
charge and discharge the external capacitor. The oscillator
waveform is a symmetrical triangular type with a typical voltage
swing between 1.0 V and 1.5 V.
fOSC ]
0.7
ROSC <COSC
Pin 11: OTS
This pin indicates an over-temperature condition on the device
when the output is low. The output is latched low and is reset
with the ENABLE pin going low then high, or by turning power
off and on.
Pin 12: ENABLE
A logic high on this pin allows normal operation. A logic low
places the chip in the standby mode. In standby mode normal
operation is disabled, supply current is reduced, the oscillator
stops and the output is held high for MODE SELECT = low, and
low for MODE SELECT = high.
Pin 13: UVLOSET
This pin will place the chip in the standby mode if the UVLOSET
voltage drops below 1.2 V. Once the UVLOSET voltage
exceeds 1.2 V, the chip operates normally. There is a built-in
hysteresis of 200 mV.
Pin 14: PGND
The negative return for the VS supply.
Pin 15: OUTPUT
This CMOS push-pull output pin drives the external MOSFET
and is capable of sinking 150 mA or sourcing 130 mA with VS
equal to 2.7 V.
Pin 16: VS
The positive terminal of the power supply which powers the
CMOS output driver. A bypass capacitor is required.
