LD7750RGN - High Voltage Green-Mode PWM Controller

This page provides the datasheet information for the LD7750RGN, a member of the LD7750R High Voltage Green-Mode PWM Controller family.

Datasheet Summary

Description

The LD7750R integrates several functions of protections, and EMI-improved solution in a SOP-7, SOP-8 or DIP-8 package to minimize the component counts and the circuit space.

Features

  • more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and OTP (Over Temperature Protection) to prevent the circuit being damaged under the abnormal conditions. The LD7750R features built-in auto-recovery function for OVP on Vcc pin and OLP. Features z High-Voltage (500V) Startup Circuit z Current Mode Control z Green Mode Control z UVLO (Under Voltage Lockout) z LEB (Leading-Edge Blanking) on CS Pin z Internal Frequency Swapping z Internal Slope Compensation z Interna.

LD7750R 05/12/2010 High Voltage Green-Mode PWM Controller with Over Temperature Protection Rev. 00 General Description The LD7750R integrates several functions of protections, and EMI-improved solution in a SOP-7, SOP-8 or DIP-8 package to minimize the component counts and the circuit space. The device provides functions of low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. Also, the LD7750R features more protections like OLP (Over Load Protection), OVP (Over Voltage Protection), and OTP (Over Temperature Protection) to prevent the circuit being damaged under the abnormal conditions. The LD7750R features built-in auto-recovery function for OVP on Vcc pin and OLP.
