AP4306BUKTR-G1

Overview

The AP4306BUKTR-G1 is a constant voltage and constant current controller for SMPS applications, manufactured by Diodes Incorporated. It integrates a 1.21V reference, a low-voltage reference (70mV), and two operational amplifiers within an SOT-26 package. The device operates on a supply voltage of 2.5V to 18V with a typical supply current of 0.5mA. It supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates precision internal voltage references and dual operational amplifiers for simplified circuit design
• Provides dedicated control loops for both constant voltage regulation and constant current limiting
• Designed for low external component count and easy compensation in power adapter systems

Applications

• Power adapters
• Battery chargers

Procurement Notes

Verify the specific suffix 'BU' against official documentation, as standard listings typically utilize 'AK'. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the selected variant matches the required 70mV current sense reference specification for the intended application.

Selection Notes

Select this component for designs requiring integrated CV/CC control without external error amplifiers. Compare performance against the AP4305 if higher power efficiency via a lower current loop reference is necessary. Verify that the SOT-26 package dimensions align with the PCB layout constraints.

Part Context

This part belongs to the AP4306 series of specialized PMICs designed for switch-mode power supplies. It serves as a highly integrated solution replacing discrete op-amp configurations, streamlining the implementation of feedback loops for regulated DC power outputs.
