    Download

    General Description

    KP1063 are a highly integrated power switch with constant current (CC) control for LED lighting applications. The IC utilizes Quasi-Resonant (QR) Buck topology with active PFC control for high PF, low THD, and high efficiency.

    KP1063 integrates 650V power MOSFET with high voltage startup and IC power supply circuit, which requires very few external components. The IC senses the inductor current during the whole switching cycle, which can achieve high precision CC control with excellent line and load regulation.

    KP1063 integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Thermal Foldack (OTP), Output Over Voltage Protection (OVP), LED Open/Short Protection, etc.
