KP1313XDP

High Efficiency QR Mode PSR CC LED Power Switch

KP1313XDP is a high efficiency Quasi-Resonant (QR) mode Primary Side Regulation (PSR) LED power switch with high precision CC control ideal for high power LED lighting applications.

KP1313XDP uses the CC loop to realize QR control and the working mechanism of the valley bottom conduction, which can greatly reduce the switching loss and improve the efficiency while improving the EMC. KP1313X integrated line voltage and load voltage CC compensation, can obtain excellent line and load regulation.

KP1313XDP integrates functions and protections of Leading Edge Blanking, VDD Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (AOCP), LED short Load Protections, and OTP.
