LD7551C - Green-Mode PWM Controller

Datasheet Summary

Description

The LD7551C is built-in with several functions, protections and an EMI-improved solution in a SOT-26 package.

It takes less components counts or circuit space, especially ideal for those cost sensitive applications.

Features

  • protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage under the abnormal conditions. Furthermore, the frequency trembling function is to reduce the noise level and help the power circuit designers for the EMI filter design with minimum component cost and developing time. Features z High-Voltage CMOS Process with Excellent ESD protection z Very Low Startup Current (.

LD7551C 4/17/2009 Green-Mode PWM Controller with Frequency Trembling and Integrated Protections REV: 00 General Description The LD7551C is built-in with several functions, protections and an EMI-improved solution in a SOT-26 package. It takes less components counts or circuit space, especially ideal for those cost sensitive applications. The LD7551C integrates low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. It also features protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage under the abnormal conditions.
