      Non-Isolated BuckBoost APFC Offline LED Power Switch
      Download

      General Description

      KP1162 is a highly integrated LED power switch with constant current (CC) control for LED lighting applications. The IC utilizes Quasi-Resonant (QR) BuckBoost topology with active PFC control for high PF, low THD, and high efficiency.

      KP1162 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 freewheeling period, which can achieve high precision CC control with excellent line and load regulation.

      KP1162 integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Thermal Foldback (OTP), Output Over Voltage Protection (OVP), LED Open/Short Protection, etc.
