R7779
Burst Triple-Mode PWM Controller with Integrated HV Start-up Device for Zero Power Monitor Application
General Description
Features
The R7779 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 R7779 provides the users a superior AC/DC power application of higher efficiency, low external component counts, and low cost solution. It features frequency jitter, Under Voltage LockOut (UVLO), Leading Edge Blanking (LEB), internal slope compensation in the tiny SOP-8 package.
