Overview
LP3773D
Low Standby Power Off-Line PSR Driver
Description
The LP3773D is a high performance AC/DC power supply controller for battery charger and adapter applications which integrated 850V high voltage BJT.
The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies.
The LP3773D provides accurate constant voltage, constant current (CV/CC) regulation without requiring opto-coupler and the secondary control circuitry.
It also eliminates the need of loop compensation circuitry while maintaining good stability.
The LP3773D can achieve excellent regulation and high average efficiency which meets no-load consumption less than 75 mW.
