AP8275
QUASI-RESONANT AC-DC CONVERTER WITH INTERNAL HV
START-UP CIRCUIT
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 package
