1 / 8 page UNISONIC TECHNOLOGIES CO., LTD UPSL101 Preliminary LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 8 Copyright © 2015 Unisonic Technologies Co., Ltd QW-R125-027.b ISOLATED, PRIMARY SIDE CONTROL LED LIGHTING DRIVER WITH ACTIVE PFC DESCRIPTION The UTC UPSL101 is a primary side control offline LED lighting controller which can achieve high power factor and accurate LED current for an isolate lighting application in a single converter. The UTC UPSL101 can control the LED current 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. And it integrates power factor correction function and works in transition mode for reducing the MOSFET switching losses. The LED current can be adjusted externally by the sense resistor RCS at CS pin. The UTC UPSL101 achieves high precision current along with excellent line regulation and load regulation. The UTC UPSL101 offers comprehensive protection coverage with auto-recovery features including VCC over voltage protection, LED open/short circuit protection, over temperature protection, over current protection, leading edge blanking, VCC under voltage lockout, VCC clamp, GATE clamp, etc. FEATURES SOP-8 * Primary-side control with single stage PFC topology * Transition mode (TM) operation to achieve high efficiency * Minimized BOM count * Cycle-by-cycle current limiting (OCP) * Selectable threshold of OCP * High current accuracy * VCC over voltage protection * Analog multiplier for power factor correction * Over-temperature protection * Output over voltage protection * LED open circuit protection * LED short circuit protection * Soft-start * Ultra-low start-up current * VCC under voltage lockout (UVLO) ORDERING INFORMATION Ordering Number Package Packing UPSL101G-S08-R SOP-8 Tape Reel UPSL101G-S08-R (1)Packing Type (2)Package Type (3)Green Package (1) R: Tape Reel (2) S08: SOP-8 (3) G: Halogen Free and Lead Free |
