KP23161SGA is a high-performance primary-side regulation (PSR) CV/CC power switch IC designed for offline flyback AC-DC power supply applications.
The device integrates a high-voltage power switching element and primary-side control technology to achieve accurate constant voltage and constant current regulation without requiring secondary-side feedback components. This reduces external components and simplifies charger and adapter designs.
KP23161SGA provides multiple protection functions including output short-circuit protection, over-voltage protection, over-current protection, over-temperature protection, UVLO, and VDD protection, improving system reliability and safety.
It is mainly used in compact mobile chargers, AC/DC adapters, and low-power flyback converter applications.
