AP3127KTR-G1

Overview

The AP3127KTR-G1 is an AC/DC converter and PWM controller manufactured by Diodes Incorporated. It operates in a flyback topology with a fixed switching frequency of 65 kHz. The device supports an input voltage range of 10 V to 28 V and features a startup voltage of 15.8 V. It provides a maximum output current of 350 mA and includes protection mechanisms for overvoltage, overload, and current limiting. The component is housed in an SOT-26 package and functions within a temperature range of -40°C to 150°C.

Feature Summary

Optimized for low-cost consumer portable products such as smartphone chargers and notebook power adapters
Integrates Green Mode functionality that reduces switching frequency at medium loads to improve system efficiency
Includes built-in fault protection features covering overvoltage, overload, and current limiting

Applications

Smartphone chargers
Notebook computer power adapters
Set-top boxes
Game consoles
Modems and networking equipment

Procurement Notes

Verify the specific suffix K against official Diodes Incorporated documentation to confirm pinout and electrical characteristics. Confirm availability status as the component may be subject to discontinuation or limited supply. Ensure compatibility with required thermal management for the specified operating temperature range.

Selection Notes

Select this component for applications requiring a cost-effective offline flyback solution with integrated control. Consider the fixed 65 kHz frequency for EMI constraints and the SOT-26 package for space-limited designs. Evaluate the need for Green Mode efficiency improvements in typical usage profiles.

Part Context

This part belongs to the AP3127 family of PWM controllers designed for AC/DC conversion. It serves as a primary side controller for isolated power supplies. The series targets high-volume consumer electronics markets where cost and performance balance are critical.
