UPSL101G-S08-R Overview

ISOLATED, PRIMARY SIDE CONTROL LED LIGHTING DRIVER WITH ACTIVE PFC

UNISONIC TECHNOLOGIES CO., LTD
UPSL101
Preliminary
LINEAR INTEGRATED CIRCUIT
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 V
CC
over voltage protection,
LED open/short circuit protection, over temperature protection,
over current protection, leading edge blanking, V
CC
under voltage
lockout, V
CC
clamp, GATE clamp, etc.
SOP-8

under voltage lockout (UVLO)
* 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
* V
CC
over voltage protection
* Analog multiplier for power factor correction
