NCP3101
NCP3101 is Wide Input Voltage Synchronous Buck Converter manufactured by onsemi.
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 k Hz 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 pensated 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.
