LC5200 - LED Drivers

Allegro MicroSystems

Datasheet Details

LC5200 series is an off-line LED driver IC which includes both a main controller integrated circuit (MIC) and a power MOSFET.

▪ 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 t.
