Introduction

AI Translation

The CN5120 is a current mode fixed-frequency PWM controller for both flyback and step-up DC-DC converters. The device operates from an input supply between 4.5V and 32V and provides to drive an external N-channel MOSFET. The CN5120 contains all the necessary building blocks including a bandgap reference, a 330KHz oscillator, current-mode control circuitry, chip shutdown block, softstart block and gate driver, etc. Current mode control provides improved transient response and simplified loop compensation. On-chip soft start reduces the inrush current on power up. The other features include chip shutdown, over voltage protection, built-in 5V regulator and slope compensation, etc. The CN5120 is available in 10-pin SSOP package.

A dedicated COMP pin allows the optimization of loop response. Soft start reduces the inrush current on power up. The internal over voltage comparator monitors the output voltage, if the output voltage is higher than nominal value by 6.5%, the DRV pin will be pulled low until the output voltage falls within 1% of nominal value.
