AP4306AKTR-G1

Overview

The AP4306AKTR-G1 is a constant voltage and constant current controller for SMPS applications. It integrates a 1.21V voltage reference, a low voltage reference (70mV), and two operational amplifiers. The device operates within an input voltage range of 2.5V to 18V and supports an operating temperature range from -40°C to +105°C. Total supply current is typically 0.5mA at 25°C. The component is housed in an SOT-26 package.

Feature Summary

• Integrates precision internal voltage references for both voltage and current control loops
• Provides low external component count requirements for adapter designs
• Features easy compensation capabilities with dedicated control loop pins

Applications

• Adapters
• Battery chargers

Procurement Notes

Verify the specific suffix 'G1' indicates RoHS compliance and halogen-free status as defined by Diodes Incorporated. Confirm the 'A' version designation corresponds to the 70mV current control loop reference voltage required for your circuit design. Ensure the SOT-26 package dimensions match your PCB footprint layout specifications.

Selection Notes

Select this component when high power efficiency is required in low-power charger applications compared to similar legacy parts. The lower current control loop reference voltage distinguishes it from functionally compatible alternatives like the AP4305. Verify that the 18V maximum supply voltage rating aligns with your primary side feedback network requirements.

Part Context

This part belongs to the AP4306 series of specialized PMICs designed for offline flyback converters. It serves as a highly integrated solution replacing discrete error amplifier and reference circuits. The device is manufactured by Diodes Incorporated and is intended for use in consumer electronics power supplies requiring precise regulation.

Replacement Considerations

The AP4305 is functionally compatible but lacks the optimized low voltage reference for current sensing found in the AP4306.
