Overview
The S-8341A50AFT-T2-U is a synchronous rectification 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 5.0 V. The device supports a maximum output current of 1.0 A with a typical quiescent current of 1.5 µA in standby mode. It features a switching frequency of 1.0 MHz and is housed in an ultra-compact HSNT-8 (2030) package measuring 2.0 mm x 3.0 mm.
Feature Summary
- Integrates high-efficiency synchronous rectification for reduced power loss
- Features ultra-low standby current consumption for extended battery life
- Includes built-in protection circuits against overcurrent, overvoltage, and thermal conditions
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered consumer electronics
- Industrial equipment with strict space constraints
Procurement Notes
Verify the specific suffix T2-U corresponds to the reel packaging configuration required for your assembly line. Confirm that the HSNT-8 package dimensions align with your PCB footprint design. Ensure the fixed 5.0 V output meets the target circuit requirements as this variant does not offer adjustable output options.
Selection Notes
Select this component when a compact form factor and high efficiency are prioritized for low-to-medium current applications. The 1.0 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the fixed 5.0 V output constraint and ensure the input voltage remains within the specified 2.7 V to 6.0 V operational range.
Part Context
This part belongs to the S-8341 series of synchronous rectification DC-DC converters from ABLIC. The series is designed for applications demanding high efficiency and minimal footprint. The HSNT-8 package represents one of the industry's smallest form factors for this class of regulators, facilitating dense PCB layouts.
Replacement Considerations
Direct substitutes may include other ABLIC synchronous buck regulators in similar packages, such as the S-8340 series or S-8353 series, provided they match the 5.0 V output and 1.0 A current capability. Verify pin compatibility and thermal performance before substitution.
