KP18108ESPA

High PF High Efficiency Stroboscopic Linear Constant Current Drive

KP18108ESPA is a high PF, high efficiency linear constant current LED driver chip, using linear constant current technology, through the external resistance to precisely set the LED lamp string current. The chip can meet the IEC-61000-3-2:2018 specification requirements. The system has excellent linear adjustment rate, and the peripheral simplification does not require magnetic components, which meets the EMI requirements, realizes small size and long life, and greatly reduces the system cost.

KP18108ESPA integrated OTP function, when the chip temperature is too high, the system will reduce the output current, to ensure the safety and reliability of the system.
