Introduction

AI Translation

The LD7552B are low cost, low startup current, current mode PWM controllers with green-mode power- saving operation. The integrated functions include the leading-edge blanking of the current sensing, internal slope compensation. They provide the users a superior AC/DC power application of higher efficiency, low external component counts, and lower cost solution. Furthermore, LD7552B feature more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to eliminate the external protection circuits. It is designed for the switching adaptor with 30W~60W output, offered in both SOP-8 and DIP-8 package.
