1 / 6 page UNISONIC TECHNOLOGIES CO., LTD UPSD1630 Preliminary CMOS IC www.unisonic.com.tw 1 of 6 Copyright © 2013 Unisonic Technologies Co., Ltd QW-R502-A01.a PSR, SINGLE STAGE, AC-DC LED DRIVER WITH ACTIVE PFC DESCRIPTION The UTC UPSD1630 is a primary-side-control AC-DC LED driver which can achieve high power factor and accurate LED current for an isolate lighting application in a single stage converter. The LED current can be controlled accurately from the primary side information. It can significantly simplify the LED lighting system design by eliminating the secondary side feedback components and the opto-coupler. The UTC UPSD1630 integrates power factor correction function and works in DCM and constant TOFF time mode for reducing the harmonic current emission (THD). The UTC UPSD1630 achieves high precision output current regulation and high power efficiency. It offers comprehensive protection coverage with auto-recovery features including VDD over voltage protection, OTP, over current protection (OCP), output over voltage protection, output short circuit protection (SCP), leading edge blanking, VDD under voltage lockout, etc. FEATURES SOP-8 * ±3% constant current regulation at universal AC input * Primary side control without TL431 and opto-coupler * Built-in power factor correction * Up to 50W power drivability * Flyback topology in DCM operation * Driver MOSFET switch * Built-in leading edge blanking * Cycle-by-cycle current limiting * Under-voltage lockout * VDD over voltage protection * Output over voltage protection * Output short circuit protection * Power on soft-start ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free UPSD1630L-S08-T UPSD1630G-S08-T SOP-8 Tube UPSD1630L-S08-R UPSD1630G-S08-R SOP-8 Tape Reel (1) R: Tape Reel (2) S08: SOP-8 (3) L: Lead Free, G:Halogen Free UPSD1630L-S08-R (1)Packing Type.
