KP13262SPA is a highly integrated LED Controller with primary side regulation (PSR) constant current (CC) control for LED lighting applications. The IC utilizes Quasi- Resonant (QR) Flyback topology with active PFC control for high PF, low THD, and high efficiency. KP13262SPA integrates high precision inductance current sampling technology and high precision current comparator for reference threshold voltage. Line and load compensation is integrated for good constant current output characteristics.KP13262SPA integrates functions and protections of VDD Under Voltage Lockout (UVLO), Cycle-by- Cycle Current Limiting (OCP), Abnormal Over Current Protection (AOCP), Adjustable Thermal Foldback (OTP), Output Over Voltage Protection (OVP), LED Protection, Line OVP/BOP etc.
