AP4313KTR-G1

Overview

The AP4313KTR-G1 is a constant voltage and constant current controller for SMPS applications, integrating a 1.21V reference (±1% accuracy), current sensing circuit, and two operational amplifiers in an SOT-26 package. It operates on a 2.5V to 18V supply with a typical supply current of 0.6mA and functions within a -40°C to +105°C temperature range.

Feature Summary

• Integrates precision internal voltage reference and dual operational amplifiers
• Provides dedicated control loops for constant voltage and constant current regulation
• Designed for low external component count and simplified compensation

Applications

• Adapters
• Battery Chargers

Procurement Notes

Verify the specific suffix 'G1' confirms compliance with RoHS 2 and Halogen/Antimony-free standards as defined by Diodes Incorporated. Confirm the 'TR' designation indicates tape and reel packaging containing 3000 units per standard factory packing quantity. Ensure the marking ID matches G6G for the specified temperature grade.

Selection Notes

Select this component when designing isolated or non-isolated power supplies requiring integrated CV/CC control. The device supports low-side current sensing via the VSENSE pin and utilizes a 200mV reference threshold. Verify that the required operating voltage falls between 2.5V and 18V and that the thermal requirements align with the SOT-26 package characteristics.
