Description

The NCP3020ADR2G is a Synchronous Pulse Width Modulation (PWM) Controller designed to operate from a wide input range and is capable of producing an output voltage as low as 0.6V. It provides integrated gate drivers and an internally set 300kHz (NCP3020A) oscillator. The NCP3020 also has an externally compensated transconductance error amplifier with an internally fixed soft-start. Protection features include lossless current limit and short circuit protection, output overvoltage protection, output undervoltage protection and input undervoltage lockout.
