KP18055ESPA

KP18055ESP is a dual-channel LED linear constant-current driver IC. Using linear constant-current technology, it requires no magnetic components in the peripheral circuit, significantly reducing system cost. KP18055ESP supports PWM dimming with deep dimming depth and high dimming accuracy, achieving flicker-free performance throughout the entire dimming range. KP18055ESP integrates an OTP function that automatically reduces the output current when the chip temperature is too high, ensuring system safety and reliability.
