R7780A - Burst Triple Mode PWM Controller

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.

Features

  • frequency jitter, Under Voltage LockOut (UVLO), Leading Edge Blanking (LEB), internal slope compensation in the tiny SOP-7 package, and offers complete protection coverage with Over Temperature Protection (OTP), Over Load Protection (OLP) and Over Voltage Protection (OVP). Ordering Information R7780A Package Type S : SOP-7 N : DIP-8 Lead Plating System G : Green (Halogen Free and Pb Free) Note : Richtek products are :  RoHS compliant and compatible with the current requirements of IPC/JEDEC J-S.
