KP2182DP is a high-performance Quasi-Resonant (QR) Primary-Side Regulation (PSR) CV/CC power switch IC designed for offline flyback charger and adapter applications.
The device integrates a 650V high-voltage MOSFET and uses primary-side control technology to achieve accurate constant voltage and constant current regulation without requiring secondary-side feedback components. It operates in quasi-resonant mode to improve efficiency, reduce switching losses, and provide better thermal performance.
KP2182DP includes advanced protection functions such as single-point failure protection, short-circuit protection, over-voltage protection, over-temperature protection, UVLO, and VDD clamp protection. It is designed for compact, high-efficiency charger and AC/DC adapter solutions.
