Product Summary

The LD7575PS is a current-mode PWM controller with excellent power-saving operation. It features a high- 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 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 applications of the LD7575PS include Switching AC/DC Adapter and Battery Charger, Open Frame Switching Power Supply, LCD Monitor/TV Power.
