Wide Input Voltage

Synchronous Buck Converter

The NCP3101 is a high efficiency, wide input, high output current,

synchronous PWM buck converter designed to operate from a 4.5 V to

13.2 V supply. The device is capable of producing an output voltage as

low as 0.8 V. The NCP3101 can continuously output 6 A through

MOSFET switches driven by an internally set 275 kHz oscillator. The

40-pin device provides an optimal level of integration to reduce size

and cost of the power supply. The NCP3101 also incorporates an

externally compensated transconductance error amplifier and a

capacitor programmable soft-start function. Protection features include

programmable short circuit protection and under voltage lockout

(UVLO). The NCP3101 is available in a 40-pin QFN package.
