1 / 9 page UNISONIC TECHNOLOGIES CO., LTD UCS3654 Advance CMOS IC www.unisonic.com.tw 1 of 9 Copyright © 2015 Unisonic Technologies Co., Ltd QW-R129-006.a DIP-8 HIGH PRECISION CC/CV PRIMARY-SIDE PWM POWER SWITCH DESCRIPTION The UTC UCS3654 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 UCS3654 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 UCS3654 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, VDD over voltage protection, VDD clamp, OTP, leading edge blanking, VDD under voltage lockout, etc. FEATURES * Built-in 650V 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 * Programmable cable compensation in CV mode * Flyback topology in DCM operation * Frequency hopping to reduce system EMI * Built-in leading edge blanking * Built-in primary winding inductance compensation * Power on soft start * Gate Output Maximum Voltage Clamped at 15V * Cycle-by-cycle current limiting * Over voltage protection * VDD under-voltage lockout ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing UCS3654L-D08-T UCS3654G-D08-T DIP-8 Tube |
