Synchronous PWM Controller

The NCP3012 is a PWM device designed to operate from a wide input range and is capable of producing an output voltage as low as 0.8 V. The NCP3012 provides integrated gate drivers and an internally set 75 kHz oscillator. The NCP3012 has an externally compensated transconductance error amplifier with an internally fixed soft−start.
