LD7537 - Green-Mode PWM Controller

Datasheet Summary

Description

The LD7537 is built-in with several functions, 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.

The implemented functions include low startup current, green-mode compensation.

Features

  • more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit damage occurred under abnormal conditions. Furthermore, the Frequency Swapping function is 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.
