R7780 - Burst Triple Mode PWM Controller

Datasheet Summary

Description

The R7780 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.

Features

  • frequency jitter, Under Voltage LockOut (UVLO), Leading Edge Blanking (LEB), internal slope compensation in the tiny SOP-7 package. It offers complete protection coverage with Over Temperature Protection (OTP), Over Load Protection (OLP) and Over Voltage Protection (OVP). Moreover, it also provides a special interface for zero power.
