Overview
LD7750E 02/29/2012 High Voltage Green-Mode PWM Controller with Over Temperature Protection Rev.
00 General Description The LD7750E 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 LD7750E 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 LD7750E features built-in auto-recovery function for OVP on Vcc pin and OLP.
