AP4306AKTR-AG1

Overview

The AP4306AKTR-AG1 is a specialized Power Management IC (PMIC) from Diodes Incorporated, designed as a Constant Voltage and Constant Current controller for SMPS applications. It operates within an input voltage range of -0.3V to 18V, with a functional supply range of 2.5V to 18V DC. The device features a minimum output voltage of 1.21V and supports a quiescent current of 0.5mA. It is housed in a SOT-26-6 surface-mount package and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Implements constant voltage and constant current control strategies for switching power supplies
• Supports wide input voltage operation up to 18V
• Designed for compact surface-mount integration

Applications

• Adapter power supplies
• Battery charger systems
• SMPS start-up circuits

Procurement Notes

Verify the specific suffix AG1 against the manufacturer's latest documentation, as it may indicate end-of-life status or specific packaging variations compared to standard G1 versions. Confirm RoHS compliance details directly with the supplier. Ensure the ordering part number matches the exact pinout and thermal requirements for your PCB layout before finalizing procurement.

Selection Notes

Select this component when designing AC/DC adapters or battery chargers requiring integrated CC/CV regulation. It is suitable for applications needing a wide input voltage range and low quiescent current. Consider the SOT-26-6 footprint constraints and ensure the thermal environment stays within the specified -40°C to +105°C operating range for reliable performance.

Part Context

This part belongs to the AP4306 series of specialized PMICs from Diodes Incorporated. It is functionally related to the AP4305 series but offers specific CC/CV control capabilities. The AP4306AKTR-AG1 variant shares the same core architecture as other AP4306 models but may differ in packaging or lifecycle status, serving as a dedicated solution for efficient power management in portable and adapter-based electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult the manufacturer's official cross-reference guide or datasheet for verified alternatives. Note that the AP4306AKTR-G1 is a related variant; however, substitution requires verification of electrical compatibility and package integrity.
