Overview
LD7752B 6/11/2013 Green-Mode PWM Controller with HV Start-Up Circuit and Soft Start time Adjustment REV.
00 General Description The LD7752B brings high performance, highly integrated functions, protections and EMI-improve solution.
It’s an ideal solution for those cost-sensitive system, reducing component count and overall system cost.
The LD7752B features high voltage startup circuit, minimum loss and green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation.
They also consist of more protections of OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit from damage under abnormal conditions.
Furthermore, the proprietary frequency swapping function can reduce the noise and help the power circuit designers to enhance EMI performance with fewer components and less developing time.
