KP18062ESPA

PF>0.7, Dual-Channel Pwm Dimming LED Linear Constant Current Drive

KP18062ESPA is a dual channel LED linear constant current driver chip, which can meet the requirements of IEC-61000-3-2:2018 specification. The chip adopts linear constant current technology and does not need magnetic components, which can greatly save the system cost.

The KP18062ESPA supports PWM dimming, has a deep dimming depth and good dimming accuracy, and can achieve no strobe in the dimming range.

KP18062ESPA integrated OTP function, when the chip temperature is too high will automatically reduce the output current, to ensure the safety and reliability of the system.
