AP4313UKTR-G1

Overview

The AP4313UKTR-G1 is a constant voltage and constant current controller designed for switch-mode power supply applications. It integrates a 1.21V voltage reference with ±1% accuracy, one current sensing circuit, and two operational amplifiers. The device operates within a supply voltage range of 2.5V to 18V and consumes a typical supply current of 0.6mA. It features a low output voltage of 200mV at 10mA sinking current and an output short-circuit current capability up to 50mA. The component functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

Integrates dual operational amplifiers and a precision internal voltage reference for combined voltage and current control loops
Provides sharp turn-on characteristics and low dynamic output impedance for stable regulation
Requires minimal external components due to high integration of control circuits
Supports easy compensation design through dedicated voltage and current control input pins

Applications

Adapters
Battery chargers
Constant voltage/constant current mode SMPS

Procurement Notes

Verify the specific suffix 'UK' against official Diodes Incorporated documentation, as standard datasheets list 'K' for SOT26 packaging. Confirm availability status, as some distributors indicate limited supply or end-of-life conditions for this part number. Ensure compliance with RoHS and halogen-free requirements by checking the latest quality definitions from the manufacturer.

Selection Notes

Select this component when a single IC solution is required for both voltage regulation and current limiting in isolated or non-isolated power supplies. The integrated dual op-amp architecture simplifies feedback loop design compared to discrete solutions. Verify that the SOT26 package dimensions fit the target PCB layout constraints and that the 18V maximum supply voltage aligns with the system's VCC rail.

Part Context

The AP4313 belongs to Diodes Incorporated's line of highly integrated power management controllers. It serves as a specialized alternative to discrete comparator and amplifier combinations in power adapter designs. The device consolidates essential control functions into a compact SOT26 package, reducing board space and component count for consumer electronics power stages.
