R7780A Description

The R7780A is a high-performance current mode PWM controller with integrated HV start-up device inside. During start-up, a current source through integrated HV device to charge VDD capacitor for quick start-up while it dissipates no loss in normal operation. The R7780A provides users a superior AC/DC power application of higher efficiency, few external ponent count, and low cost solution.
