Overview

UNISONIC TECHNOLOGIES CO.
, LTD UPSRB02 Preliminary LINEAR INTEGRATED CIRCUIT HIGH PRECISION CC/CV PRIMARY SIDE SWITCHING REGULATOR  DESCRIPTION The UTC UPSRB02 is a primary control unit for switch mode 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) and Pulse Width Modulation (PWM) method to build discontinuous conduction mode (DCM) flyback power supplies.
The UTC UPSRB02 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...
