Preliminary
PSR, SINGLE STAGE, AC-DC
LED DRIVER WITH ACTIVE
PFC
CMOS IC
 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.
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 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.
