LD5532 - Green-Mode PWM Controller

Datasheet Summary

Description

The LD5532 is built with several functions, audio noise prevention, protection and EMI-improved solution in a tiny package.

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

Features

  • protections of OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit from damage under abnormal conditions. Furthermore, the Frequency Swapping function is also built-in to reduce the noise level and thus helps the power circuit designers to easily deal with the EMI filter design by spending minimum amount of component cost and developing time. Features.
  • High-Voltage CMOS Process with Excellent ESD protection.
  • Very Low Startup Current (.

LD5532 07/08/2014 Green-Mode PWM Controller with Frequency Swapping and Audio Noise Prevention REV. 00 General Description The LD5532 is built with several functions, audio noise prevention, protection and EMI-improved solution in a tiny package. It takes less components counts or circuit space, especially ideal for those total solutions of low cost. It includes low startup current, green-mode power-saving operation, leading-edge blanking of the current sense and internal slope compensation. It also features protections of OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit from damage under abnormal conditions.
