CR6237 - High Precision CC/CV Primary-Side PWM Power Switch

This page provides the datasheet information for the CR6237, a member of the CR6235 High Precision CC/CV Primary-Side PWM Power Switch family.

Datasheet Summary

Description

CR623X is a high performance offline PWM power switch for low power AC/DC charger and adaptor applications.

It operates in primary-side sensing and provides constant voltage (CV) and constant current (CC) regulation without TL431 and opto-coupler.

A typical output CC/CV curve is shown as in the Fig.

Features

  • Up to 5% Precision for Constant Voltage Regulation and Constant Current Regulation at Universal AC input Primary-side Sensing and Regulation Without TL431 and Opto-coupler Flyback Topology In DCM Operation Soft-start Built-in Leading Edge Blanking (LEB) Frequency Jitter to Reduce System EMI Programmable CV and CC Regulation Adjustable Constant Current and Output Power Setting Built-in Secondary Constant Current.
