Product Description

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.

Main feature

• High PF>0.7, no stroboscopic application

• Meet IEC-61000-3-2:2018 specification requirements

• Integrated 800V rectifier bridge

• Set the output constant current to 5 to 60mA

• Constant current accuracy deviation between chips ±4%

• Application solution has no EMI problem

• Simple wiring, low power system cost

• Internal protection functions:

• Overheat protection (OTP)

• Encapsulation type HSOP-8

Typical application

• LED filament light

• LED bulb light, downlight
