Synchronous PWM Controller

Favorite

Overview

The NCP3020 is a Synchronous Buck Controller (PWM Controller) designed to operate from a wide input range and is capable of producing an output voltage as low as 0.6 V. The NCP3020A provides integrated gate drivers and an internally set 300 kHz oscillator (600 kHz for the NCP3020B).

The NCP3020 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. The NCP3020 is currently available in a SOIC-8 package.
