Overview

LC5200 Series LED Drivers 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 ▪ The...
