Overview
The S-8340A25AFT-T2-U is a synchronous step-down switching regulator manufactured by ABLIC Inc. It operates within an input voltage range of 2.7 V to 6.0 V and provides a fixed output voltage of 2.5 V. The device supports a maximum output current of 1.5 A and features a switching frequency of 2.2 MHz. It utilizes a compact SOT-23-5 package and functions reliably across an operating temperature range from -40 °C to +85 °C.
Feature Summary
- Synchronous rectification architecture for high conversion efficiency
- Integrated power MOSFETs to minimize external component count
- Fixed internal switching frequency for stable operation
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered systems with single-cell lithium-ion inputs
- Embedded logic circuits needing regulated low-voltage supplies
Procurement Notes
Verify the specific suffix 'T2-U' against official ABLIC documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SOT-23-5 footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's latest product declaration before finalizing procurement orders.
Selection Notes
Select this component when a compact solution is required for stepping down single-cell battery voltages to 2.5 V. The 2.2 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current does not exceed the 1.5 A limit under all thermal conditions.
Part Context
This part belongs to the S-8340 series of synchronous buck converters designed for portable applications. The series emphasizes small footprint and high efficiency, making it suitable for space-constrained designs. It represents ABLIC's focus on integrated power management solutions for consumer electronics.
Replacement Considerations
Consult official cross-reference lists for direct replacements. Verify pinout compatibility and electrical parameters such as output voltage tolerance and current limits before substituting.
