R7780 Datasheet Burst Triple Mode PWM Controller

Manufacturer: Richtek

General 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.

The R7780 provides the users a superior AC/DC power application of higher efficiency, few external component counts, and low cost solution.

Overview

R7780 Burst Triple Mode PWM Controller with Integrated HV Start-up Device for Zero Power Monitor Application.

Key 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.
