LC5200 Series
Off-Line LED Driver ICs
Features and Benefits
▪ Buck topology
▪ High input voltage: up to 250 V or 450 V, depending on
product
▪ Constant current control circuit:
▫ Fixed off-time PWM constant current control, off-time
adjustable by external components
▫ Externally adjustable output current by input voltage to
REF pin
▪ External PWM signal:
▫ Dimming controlled by PWM signal to PWM pin
▫ Turning off LEDs by low input voltage to PWM pin
▪ Protection features:
▫ Undervoltage lockout protection (UVLO)
▫ Overcurrent protection (OCP) with latched shutdown
▫ Thermal shutdown protection (TSD) with auto restart

Description
The LC5200 series is a power IC, for non-isolated LED driver
with commercial power supply applications, which includes
both a main controller integrated circuit (MIC) and a power
MOSFET. Its high voltage capability allows direct connection
to a wide range of supply voltages ranging from 25 to 400 V
(recommended). The LC5200 uses constant current mode to
drive LEDs. The LC5200D series package is a fully molded
DIP8 with pin 7 removed for greater isolation, and the LC5200S
series package is an SOP8.
Applications
▪ LED lighting fixtures
▪ LED light bulbs
