US3602G-S08-R Overview

HIGH PRECISION PSR CONSTANT CURRENT LED DRIVER

UNISONIC TECHNOLOGIES CO., LTD
US3602
Preliminary
CMOS IC
HIGH PRECISION PSR
CONSTANT CURRENT
LED DRIVER
DESCRIPTION
The
UTC US3602
is a primary side control offline LED lighting
controller. It operates in inductor current DCM mode and can
achieve accurate constant current.
The
UTC US3602
integrates 600V power MOSFET and
simplifies the LED lighting system design by eliminating the
secondary side feedback components and the opto-coupler. The
loop compensation components are also removed while
maintaining stability overall operating conditions.
The LED current can be adjusted externally by the sense
resistor RCS at CS pin. The
UTC US3602
achieves ±3% accuracy
of LED current along with excellent line regulation and load
regulation.
The
UTC US3602
offers comprehensive protection coverage
with auto-recovery features including LED short circuit protection,
LED open circuit protection, Cycle-by-cycle current limiting, OTP,
V
CC
over voltage protection, leading edge blanking, V

If the 28069 CLA performs 32-bit fixed-point multiplication, will the execution efficiency be very low?
Define two 32-bit fixed-point (int32) variables X and Y in CLARAM2. Both CPU and CLA can read and write X and Y. Assign values to X and Y in CPU and calculate Z = X*Y in CLA. Z is also a 32-bit fixed-...
