Overview
UNISONIC TECHNOLOGIES CO.
, LTD UPSR100 Preliminary HIGH PRECISION CC/CV PRIMARY SIDE REGULATOR CMOS IC  DESCRIPTION The UTC UPSR100 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) method to build discontinuous conduction mode (DCM) flyback power supplies.
The UTC UPSR100 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 UPSR100 achieves high precision CV/CC regulation and ...
