AP4306AUKTR-G1

Overview

The AP4306AUKTR-G1 is a constant voltage and constant current controller for SMPS applications, manufactured by Diodes Incorporated. It integrates a 1.21V voltage 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 supply architectures.

Applications

Adapters
Battery chargers

Procurement Notes

Verify the specific suffix 'G1' confirms RoHS compliance and halogen-free status as defined by the manufacturer. Confirm the 'A' version designation corresponds to the 70mV current control loop reference voltage required for the application. Ensure the SOT-26 package type matches the PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when high efficiency is required in low-power charger designs compared to similar legacy parts. The AP4306 offers a lower reference voltage for the current control loop than the AP4305, enabling optimized performance. Verify that the 70mV sense threshold aligns with the chosen current sensing resistor values for the target load requirements.

Part Context

This part belongs to the AP4306 series of specialized PMICs designed for AC/DC conversion. It serves as a highly integrated solution for managing power delivery in switching mode power supplies. The device replaces discrete amplifier and reference solutions, reducing board space and complexity in consumer electronics power stages.
