Overview
The AP4320AK6TR-G1 is a constant voltage and constant current controller for SMPS applications, housed in an SOT-26 package. It integrates a 2.5V precision internal voltage reference and two operational amplifiers to facilitate easy compensation and low external component count. The device operates within a supply voltage range of 3.5V to 36V with a typical supply current of 190µA. It features a low current-sense threshold of 30mV for the 'A' variant, enabling precise output low-side current sensing.
Feature Summary
- Integrates a 2.5V precision internal voltage reference combined with two operational amplifiers for simplified control loop design.
- Provides dedicated constant voltage and constant current control capabilities suitable for adapters and battery chargers.
- Features a low current-sense threshold of 30mV for accurate output low-side current sensing.
- Designed for low external component count and easy compensation in switching power supply topologies.
Applications
- AC/DC adapters
- Battery chargers
- LED drivers
Procurement Notes
Verify the specific suffix 'AK6' confirms the 30mV current sense threshold variant and SOT-26 packaging. Confirm RoHS compliance and Halogen-free status requirements against project specifications. Ensure the operating supply voltage remains within the 3.5V to 36V range during system design validation.
Selection Notes
Select this component when a highly integrated solution for constant voltage and constant current modes is required. The AP4320AK6TR-G1 is appropriate for designs needing a 30mV current sense threshold. Consider the 190µA supply current and 3.5V minimum operating voltage for low-power or battery-fed systems.
Part Context
This part belongs to the AP4320 series of constant voltage and constant current controllers manufactured by Diodes Incorporated. The 'A' suffix denotes the 30mV current sense threshold variant, while 'K6' specifies the SOT-26 surface-mount package. It serves as a specialized PMIC for managing power conversion loops in compact electronic devices.
Replacement Considerations
The AP4320BK6TR-G1 is a confirmed substitute offering identical functionality but with a 50mV current-sense threshold. Verify that the higher threshold meets the application's current limiting requirements before substitution.
FAQ
What is the difference between the AP4320A and AP4320B variants?
The primary difference lies in the current-sense threshold. The AP4320A (suffix A) has a 30mV threshold, while the AP4320B (suffix B) has a 50mV threshold.
Does the AP4320 support high-side current sensing?
No, the datasheet specifies that the AP4320 is designed for output low-side current sensing using its integrated operational amplifier and current control loop.
