• Industrial control systems utilizing single-cell lithium-ion or lithium-polymer batteries
• Consumer electronics needing compact power supply solutions

Procurement Notes

Verify the specific suffix 'T2-G' against the manufacturer's official datasheet to confirm the tape-and-reel packaging quantity and RoHS compliance status. Ensure the ordering documentation matches the exact part number to avoid discrepancies in package type or environmental certifications. Cross-reference the manufacturer's latest release notes for any potential obsolescence notices or alternate pin-compatible recommendations.

Selection Notes

Select this component when a compact boost converter solution is required for single-cell battery applications. The fixed 2.5 V output simplifies design by eliminating external feedback resistors. Consider the 1.5 A peak current capability for moderate load requirements. Verify that the TSSOP-B8 package fits the available PCB footprint and thermal constraints of the target enclosure.

Part Context

This part belongs to the S-8340/8341 series of CMOS step-up switching regulators. The series is characterized by its integration of essential power management functions into a small footprint. It targets applications where space efficiency and high conversion performance are critical. The S-8341 variant specifically offers fixed output options to streamline circuit design.

Replacement Considerations

Check the official ABLIC cross-reference list for direct replacements. Verify compatibility of the TSSOP-B8 package and electrical specifications such as input voltage range and switch current limits before substitution.
