LD7550 Datasheet (ETC) - Green-Mode PWM Controller

LD7550, Green-Mode PWM Controller

The LD7550 is a low cost, low startup current, current mode PWM controller with green-mode power-saving operation.

The integrated functions such as the leading-edge blanking of the current sensing, internal slope compensation and the small SOT-26 package provide the users a high efficiency, low exte
