DESCRIPTION

The AP8275 consists of an integrated current mode Pulse Width Modulator (PWM) controller and high voltage start circuit, specifically designed for a high performance off-line converter with minimal external components. QR-PWM, QR-PFM, Burst-mode operation and low consumption device help to meet the standby energy saving standards and achieve higher efficiency. Excellent EMI performance is achieved by frequency modulation and soft driver technique. The AP8275 offers completed and excellent protections including Brown-in/out, AC Line OVP, X-cap discharge, output over voltage protection, external over temperature protection, Cycle-by-Cycle current limiting, over load protection.

The

AP8275 is available in SOP7 p ackage
