UPSL1630

Preliminary

CMOS IC

PSR, SINGLE STAGE, AC-DC

LED DRIVER WITH ACTIVE

PFC



DESCRIPTION

The UTC UPSL1630 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.

SOP-8

The UTC UPSL1630 integrates power factor correction function

and works in DCM and constant TOFF time mode for reducing the

harmonic current emission (THD).

The UTC UPSL1630 achieves high precision output current

regulation and high power efficiency. It offers comprehensive

protection coverage with auto-recovery features including V_DDover

voltage protection, OTP, over current protection (OCP), output over

voltage protection, output short circuit protection (SCP), leading

edge blanking, V_DDunder voltage lockout, etc.



FEATURES

* ±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

* Cycle-by-cycle current limiting

* Under-voltage lockout

* V_DDover voltage protection

* Output over voltage protection

* Output short circuit protection

* Power on soft-start

* Built-in leading edge blanking
