Leadtrend    LD7552IS  LD7552  Green-Mode PWM Controller SOP-8

Description:

The LD7552IS 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 package provide the users a high efficiency, minimum external component counts, and low cost solution for AC/DC power applications. The special green-mode control does not only achieve low power consumption but also offer a non-audible-noise operation when the LD7552IS operates under light load or no load condition. The LD7552 is designed for the switching adaptor with 30W~60W output. The LD7552IS is offered in both SOP-8 package.
