Overview
The AP4320BK6TR-G1 is a highly integrated constant voltage and constant current controller designed for switch-mode power supply applications. It incorporates a precision internal 2.5V voltage reference, two operational amplifiers, and a low-voltage current-sense threshold of either 30mV or 50mV. The device operates on a supply voltage ranging from 3.5V to 36V with a typical supply current of 190µA. Packaged in an SOT-26 surface-mount format, it provides a compact solution for adapters, battery chargers, and LED drivers.
Feature Summary
- Integrates a 2.5V precision voltage reference and dual operational amplifiers for combined voltage and current regulation
- Supports low-side current sensing with selectable 30mV or 50mV thresholds
- Requires minimal external components to facilitate easy compensation and design
- Operates within a wide supply voltage range while maintaining low quiescent current consumption
Applications
- AC/DC adapters
- Battery chargers
- LED drivers
Procurement Notes
Verify the specific suffix 'B' indicates the 50mV current sense threshold variant when sourcing this component. Confirm the package marking ID 'GKW' matches the required inventory specifications. Ensure the tape and reel packaging aligns with automated assembly requirements. Cross-reference the RoHS compliance status against current environmental regulations before finalizing procurement orders.
Selection Notes
Select the AP4320BK6TR-G1 when a 50mV current sense threshold is required for low-side sensing applications. This part integrates both voltage and current control loops into a single SOT-26 package, reducing board space compared to discrete solutions. Verify that the operating supply voltage remains within the 3.5V to 36V range for optimal performance during system design.
Part Context
This component belongs to the AP4320 family of constant voltage and constant current controllers manufactured by Diodes Incorporated. The 'K6' designation specifies the SOT-26 surface-mount package, while the 'G1' suffix denotes a halogen-free and antimony-free green device compliant with RoHS directives. The 'B' suffix specifically identifies the version with a 50mV current sense threshold.
Replacement Considerations
The AP4320AK6TR-G1 serves as a direct substitute if a 30mV current sense threshold is preferred instead of the 50mV threshold found in the AP4320BK6TR-G1. Both variants share identical pinouts, packages, and electrical characteristics except for the current sense reference level.
FAQ
What is the difference between the AP4320AK6TR-G1 and AP4320BK6TR-G1?
The primary difference lies in the current sense threshold. The AP4320AK6TR-G1 features a 30mV threshold, whereas the AP4320BK6TR-G1 has a 50mV threshold.
How does the AP4320 handle current limiting?
It uses one of its internal operational amplifiers combined with the low-voltage reference to monitor output low-side current sensing, acting as an ideal current limiter.
