AP3983CMTR-G1

Overview

The AP3983CMTR-G1 is an AC/DC converter and power switcher designed for offline flyback applications. It integrates a high-voltage MOSFET and control circuitry to support primary-side regulation (PSR) topologies. The device operates with a switching frequency of 80 kHz and supports output power up to 10 W. It features a wide supply voltage range from 6.82 V to 25 V and includes built-in protection mechanisms such as over-temperature, over-voltage, and short-circuit protection. The component is housed in a 7-SO package.

Feature Summary

• Integrates primary-side regulation capability for simplified transformer design
• Includes comprehensive protection against thermal overload, over-voltage, and short circuits
• Features internal high-voltage startup circuitry for efficient operation

Applications

• Adapters
• Offline converters
• Flyback topology power supplies

Procurement Notes

Verify current availability status as the component may be subject to discontinuation notices. Confirm RoHS compliance and moisture sensitivity level requirements prior to ordering. Ensure the specific suffix matches the required packaging format. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain unchanged for your design integration.

Selection Notes

Select this component for designs requiring integrated PSR solutions to reduce external feedback components. Consider the 80 kHz switching frequency for balancing efficiency and EMI performance. Evaluate the 10 W power limit against load requirements. Verify that the 7-SO package fits the PCB layout constraints and thermal management strategy.
