Overview

UNISONIC TECHNOLOGIES CO.
, LTD USRB01 Preliminary LINEAR INTEGRATED CIRCUIT HIGH PRECISION CC/CV PRIMARY SIDE SWITCH  DESCRIPTION The UTC USRB01 is a primary controller for charger and adapter applications.
The controlled variable is transferred by an auxiliary winding from the secondary to the primary side.
The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies.
The UTC USRB01 operates in primary-side sensing and regulation.
Opto-coupler and TL431 could be eliminated.
It also eliminates the need of loop compensation circuitry while maintaining stability.
The UTC USRB01 achieves high precision CV/CC regulation and hi...
