DESCRIPTION

KP1274JDP is a PF>0.9, high accuracy constant current LED driver. It is suitable for non-isolated step-down constant current LED driver application at universal input voltage. It is operated at Quasi-Resonant (QR) mode with active PFC control for high PF, low THD, and high efficiency.KP1274JDP integrates a 500V high-voltage power MOSFET, and loop compensation circuits. It is supplied from the line directly without auxiliary winding or external capacitor, which can lower the system BOM cost. With unique sampling techniques and internal compensation techniques, it can maintain good constant current accuracy and excellent line and load regulations.KP1274JDP has multiple protection functions, which can largely enhance the safety and reliability of the system, including cycle-by-cycle current limiting, LED open/short protection, Output Over Voltage Protection (OVP), Thermal Fold-back (OTP), etc.
