LD7552BS LD7552BPS sop8 LCD power  

The LD7552B are low cost, low startup current, current
mode PWM controllers with green-mode power- saving
operation. The integrated functions include the
leading-edge blanking of the current sensing, internal slope
compensation. They provide the users a superior AC/DC
power application of higher efficiency, low external
component counts, and lower cost solution.
Furthermore, LD7552B feature more protections like OLP
(Over Load Protection) and OVP (Over Voltage Protection)
to eliminate the external protection circuits. It is designed for
the switching adaptor with 30W
