Product Description

The KP2801ASGA is a high-performance quasi-resonant (QR) Boost Power Factor Correction (PFC) controller designed for high-efficiency AC-DC power conversion applications. It automatically switches between Critical Conduction Mode (CRM) and Discontinuous Conduction Mode (DCM) to optimize efficiency across varying load conditions while delivering high power factor (PF) and low total harmonic distortion (THD).
The device integrates a 700V high-voltage startup circuit, eliminating the need for an external startup resistor and simplifying system design. Comprehensive protection features ensure reliable operation, making the KP2801ASGA ideal for LED drivers, adapters, battery chargers, and industrial power supplies.
