AP8275 Datasheet | AiT Semiconductor

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 - - ponents. 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 pleted 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 65/85k Hz AC Brown-in/out protection X-cap discharge function (Pass IEC62368-1:2014 certification） No-load consumption power < 50m W @230VAC Proprietary Frequency Jitter for EMI VDD Operating voltage range 8~40V Adjustable AC Line Input pensation 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 ORDERING INFORMATION APPLICATION Package Type Part Number SOP7 M7 AP8275M7VR SPQ: 4,000pcs/Reel Note V: Halogen free Package R: Tape & Reel Ai T provides all Ro HS products - Stand-by power - Open-frame SMPS - Adaptor TYPICAL APPLICATION REV1.1 - FEB 2019 RELEASED - DEC 2022 REVISED -- -1- Ai T Semiconductor Inc. .ait-ic.
