LD7750RGS - High Voltage Green-Mode PWM Controller

Download the LD7750RGS datasheet PDF. This datasheet also covers the LD7750R variant, as both devices belong to the same high voltage green-mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

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.

Key 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.
