The LD7575 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 the bulk capacitor and further 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 with high efficiency, minimum external component counts, and low-cost solutions for AC/DC power applications. Furthermore, the embedded over-voltage protection, overload protection, and exceptional green-mode control provide the solution for users to design a high-performance power circuit easily. The LD7575 is offered in both SOP-8 and DIP-8 package.
