DESCRIPTION
FEATURES
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.
