DESCRIPTION

The UTC UCSR3651S is a primary control switch 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

discontinuous conduction mode (DCM) flyback converters.

The UTC UCSR3651S 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.

SOP-8

The UTC UCSR3651S achieves high precision CV/CC

regulation and high power efficiency. It offers comprehensive

protection coverage with auto-recovery features including

Cycle-by-cycle current limiting, V_DDover voltage protection, V_DD

clamp, OTP, leading edge blanking, V_DDunder voltage lockout, etc.



FEATURES

* Built-in leading edge blanking

* High Voltage startup circuit

* Built-in primary winding inductance

compensation

* Gate Output Maximum Voltage Clamped at

15V

* Built-in 600V Power MOSFET

* ±5% constant voltage regulation at universal AC input

* High precision constant current regulation at universal AC input

* Primary side control without TL431 and opto-coupler

* Programmable CV and CC regulation

* Cycle-by-cycle current limiting

* Over voltage protection

* V_DDunder-voltage lockout

* Programmable cable compensation in CV mode

* Flyback topology in DCM operation

* Frequency hopping to reduce system EMI
