FEATURES AND BENEFITS
● Supply voltage, VBB, 450 V maximum, 25 to 400 V recommended; Note: lowest voltage can vary depending on LED loads● Output current IO(max) options: ▫ 0.5 A, LC5205D ▫ 1.0 A, LC5210D
● 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
● Output current dimming by external PWM signal; low signal to TOFF pin shuts off output current, and PWM signal input to that pin enables dimming
● Undervoltage lockout protection (UVLO)
● Overcurrent protection (OCP); latched in response to the short-to-GND condition
● Thermal Shutdown protection (TSD); protects IC from damage due to excess temperature, auto-restart when temperature drops below threshold
DESCRIPTION
LC5200 series is an off-line LED driver IC 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).
