LD7751
LD7751 is High Voltage Green-Mode PWM Controller manufactured by Leadtrend.
Description The LD7751 integrates several functions of protections, and EMI-improved solution in a SOP-7, SOP-8 or DIP-8 package to minimize the ponent 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 pensation. Also, the LD7751 features more protections like OLP (Over Load Protection), and OVP (Over Voltage Protection) to prevent the circuit being damaged under the abnormal conditions. The LD7751 features built-in auto-recovery function for OVP on Vcc pin and OLP.
