NCP3101: Synchronous Buck Regulator, PWM, 6.0 A
The NCP3101 is a high efficiency, wide input, high output current, synchronous Pulse Width Modulation (PWM) buck regulator designed to operate from a 2.7 V to 18 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. Also available in a 10A version NCP3102.NCP3101 will be replaced by NCP3101C per PCN#16498
