General Description

The LD7531 is built-in with several functions, protection and EMI-improved solution in a SOT-26/ DIP-8 package.

It takes less components counts or circuit space, especially ideal for those total solutions of low cost.

The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation.

Overview

LD7531 6/25/2008 Green-Mode PWM Controller with Frequency Trembling and Integrated Protections REV: 00.

Key Features

more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage from the abnormal conditions. Furthermore, the frequency trembling function is to reduce the noise level and thus helps the power circuit designers to easily deal with the EMI filter design by using minimum component cost and developing time.
