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.

SOP-8

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_CCover voltage protection,

LED open/short circuit protection, over temperature protection,

over current protection, leading edge blanking, V_CCunder voltage

lockout, V_CCclamp, GATE clamp, etc.



FEATURES

* Primary-side control with single stage PFC topology

* Cycle-by-cycle current limiting (OCP)

* Selectable threshold of OCP

* Over-temperature protection

* Output over voltage protection

* LED open circuit protection

* LED short circuit protection

* Soft-start

* High current accuracy

* V_CCover voltage protection

* Ultra-low start-up current

* V_CCunder voltage lockout (UVLO)

* Analog multiplier for power factor correction
