S-8340B00AFT-T2-G

Overview

The S-8340B00AFT-T2-G is a switching voltage regulator manufactured by ABLIC Inc. It operates within an input voltage range of 2.5 V to 16 V and delivers a fixed output voltage of 5.0 V. The device utilizes pulse width modulation (PWM) control with a typical switching frequency of 1.2 MHz. It is housed in an 8-pin TSSOP package and supports surface mount installation. The component functions as a step-up converter, designed for efficient power management in portable electronic applications requiring stable voltage regulation from varying input sources.

Feature Summary

• Integrates a high-efficiency internal power switch for compact circuit design
• Employs PWM control technology to maintain stable output under varying load conditions
• Features built-in protection mechanisms against thermal overload and low input voltage

Applications

• Portable battery-powered devices requiring voltage boosting
• General-purpose DC-DC conversion in consumer electronics
• Power supply stages in mobile communication equipment

Procurement Notes

Verify the specific suffix T2-G against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status through current documentation. Cross-reference the full part number with authorized distributors to validate availability and authenticity before procurement.

Selection Notes

Select this component when a fixed 5.0 V output is required from an input range of 2.5 V to 16 V. The 1.2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the TSSOP-8 package constraints for PCB layout. Verify that the maximum output current requirements align with the device's internal switch capabilities and thermal performance limits.

Part Context

This part belongs to the S-8340 series of switching regulators from ABLIC Inc. The series focuses on step-up voltage conversion for portable applications. The S-8340 family typically integrates power switches and control logic into a single compact package. This specific model provides a fixed 5.0 V output, distinguishing it from adjustable variants within the same product line.

Replacement Considerations

Consult official substitution guides for equivalent step-up regulators with similar input ranges and fixed 5.0 V outputs. Verify pinout compatibility and electrical characteristics such as switching frequency and output current capacity before replacing.
