Overview
UNISONIC TECHNOLOGIES CO.
, LTD UPSR108 Preliminary HIGH PRECISION CC/CV PRIMARY-SIDE PWM CONTROLLER WITH FAST DYNAMIC RESPONSE  DESCRIPTION The UTC UPSR108 is a primary controller mode charger and adapter applications.
The controlled variable is transferred by an auxiliary winding from the secondary to the primary side.
The device integrates PWM controller to enhance the performance of Quasi Resonant (QR) mode flyback converters.
The UTC UPSR108 operates in primary-side sensing and regulation.
Opto-coupler and TL431 could be eliminated.
It also provides off-time modulation to linearly decrease PWM frequency under light-load conditions so that low standby power can be achieved.
The UTC UPSR108 integrates functions and protections of Under Voltage Lockout (UVLO), VDD Over Voltage Protection (VDD OVP), Output Over Voltage Protection (Output OVP), OTP, Soft Start, Cycle-by-cycle Current Limiting (OCP), Pin Floating Protection, Gate Clamping, VDD Clamping.
