LD7575A Green-Mode PWM Controller

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.
