AP8275
Key Features
- 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, 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 Internal HV Start-up Circuit Multi-mode operation to achieve higher efficiency Adaptive PWM switching frequency 65/85kHz AC Brown-in/out protection X-cap discharge function (Pass IEC62368-1:2014 certification） No-load consumption power < 50mW @230VAC Proprietary Frequency Jitter for EMI VDD Operating voltage range 8~40V Adjustable AC Line Input Compensation Excellent Protection Coverage -Over Temperature Protection（OTP） -Output over voltage protection -Cycle-by-cycle Over Current Protection（OCP） -Output Open/short Protection -Patented DMG resistor short protection（Latch） -Secondary Rectifier Short Protection -Over Load Protection（OLP） -Available in SOP7 Package
