LD7575A 11/29/2007 Green-Mode PWM Controller with High-Voltage Start-Up Circuit Rev.00a General Description The LD7 575A is a c urrent-mode PWM con troller with tures a highexcellent pow er-saving o peration. It fea voltage current source to directly supply the startup current from bulk capacitor and further to provide a lossless startup circuit. The integrated functions such as the le ading-edge blanking of the current sensing, internal slope compensation, and the small package provide the users a high effic iency, minimum external component counts, and low cost solution for AC/DC power applications.
