Overview
The AP3983RMTR-G1 is an AC/DC converter IC from Diodes Incorporated, designed for offline flyback applications. It operates with a switching frequency of 80 kHz and supports a supply voltage range of 6.82 V to 25 V. The device features an internal 700 V breakdown switch and utilizes piecewise Pulse Frequency Modulation (P-PFM) technology in discontinuous conduction mode. It provides output isolation and includes protection against over-temperature, over-voltage, and short circuits. The component is housed in a 7-SO package and is rated for junction temperatures up to 150°C.
Feature Summary
- Integrates high-voltage power switch with built-in fault protection mechanisms
- Employs piecewise pulse frequency modulation for precise regulation
- Supports isolated output configurations for safety compliance
Applications
- Charger designs
- ADSL adapter power supplies
- Household appliance power systems
