LD7550 Description
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 pensation and the small SOT-26 package provide the users a high efficiency, low external ponent counts, and low cost solution for AC/DC power applications. The special green-mode control is not only to...
