Overview
The AP4306BUKTR-E1 is a constant voltage and constant current controller manufactured by Diodes Incorporated. It integrates a 1.21V voltage reference, a low voltage reference for current sensing, and two operational amplifiers within an SOT26 package. The device operates with a supply voltage range of 2.5V to 18V and supports an operating temperature range from -40°C to +105°C. It features a total supply current of 0.5mA and utilizes a 70mV reference for the current control loop.
Feature Summary
- Provides integrated constant voltage and constant current control capabilities
- Includes precision internal voltage references for accurate regulation
- Designed for low external component count and simplified compensation
- Operates with low supply current consumption
Applications
- Adapters
- Battery chargers
Procurement Notes
Verify that the specific ordering suffix matches the required configuration. Confirm the package type is SOT26 and the version corresponds to the 70mV current control loop reference. Ensure compliance with RoHS and lead-free requirements as specified in the datasheet notes before finalizing procurement.
Selection Notes
Select this component for SMPS applications requiring high integration. It offers higher power efficiency compared to the AP4305 due to its lower current control loop reference voltage. Suitable for designs needing precise voltage regulation and low side current sensing without additional discrete components.
Part Context
This part belongs to the AP4306 series of constant voltage/constant current controllers. It is functionally compatible with the AP4305 but provides improved efficiency through a reduced reference voltage for the current control loop. The series is designed for compact power management solutions in consumer electronics.
Replacement Considerations
The AP4305 is functionally compatible but lacks the lower reference voltage for the current control loop found in the AP4306. Substitution may require re-evaluation of current sensing circuitry to maintain optimal efficiency.
