LC5200 Overview
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 (remended). The LC5200 uses constant current mode to drive LEDs.
LC5200 Key Features
- Supply voltage, VBB, 450 V maximum, 25 to 400 V remended; 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 ponents
- Output current dimming by external PWM signal; low signal to TOFF pin shuts off output current, and PWM signal input to
- 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 drop
