PartNumber: None
The KP2182LGA is a high-performance quasi-resonant (QR) Primary-Side Regulated (PSR) constant-voltage/constant-current (CV/CC) controller designed for offline flyback AC-DC power supplies, especially battery chargers and power adapters. It operates in quasi-resonant mode under full-load conditions to achieve high efficiency, low EMI, and low temperature rise. The device provides accurate CV/CC regulation without requiring an optocoupler and incorporates comprehensive protection features for reliable operation.
