UPSR107

Preliminary

CMOS IC

HIGH PRECISION CC/CV

PRIMARY-SIDE PWM

CONTROLLER



DESCRIPTION

The UTC UPSR107 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.

SOT-26

The UTC UPSR107 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 UPSR107 integrates functions and protections of

Under Voltage Lockout (UVLO), V_DDOver Voltage Protection (V_DD

OVP), Output Over Voltage Protection (Output OVP), OTP, Soft

Start, Cycle-by-cycle Current Limiting (OCP), Pin Floating

Protection, Gate Clamping, V_DDClamping.
