Overview
The S-8340A35AFT-T2-G is a DC-DC switching controller manufactured by ABLIC Inc. It functions as a step-up regulator with a fixed output voltage of 3.5V and operates at a switching frequency of 600kHz. The device supports an input voltage range suitable for boosting lower supply rails to the required output level. It utilizes a TSSOP-8 package for surface mount installation. The component is currently classified as obsolete in distributor catalogs.
Feature Summary
- Integrated PWM control for efficient step-up voltage conversion
- Built-in shutdown functionality for power management
- Positive output configuration
Applications
- Portable electronic devices requiring battery voltage boosting
- Embedded systems needing stable 3.5V logic supplies
- Industrial equipment with varying input voltage ranges
Procurement Notes
This part number is listed as obsolete by major distributors. Verification of final time status and availability of last-time buys is essential before design finalization. Confirm if alternative revisions or pin-compatible successors are available from ABLIC Inc. to ensure long-term supply chain stability for production runs.
Selection Notes
Designers should evaluate current alternatives due to the obsolete status of this specific revision. Consider the S-8340 series variants that remain active, ensuring compatibility with existing PCB footprints and thermal requirements. Verify that the 600kHz switching frequency aligns with electromagnetic interference constraints in the target application environment.
Part Context
The S-8340 series represents ABLIC's line of high-efficiency DC-DC converters designed for compact power solutions. This specific model targets applications requiring a reliable 3.5V output from lower input sources. The TSSOP-8 packaging allows for dense board layouts, making it suitable for space-constrained consumer and industrial electronics where size efficiency is critical.
Replacement Considerations
Check for active S-8340 series equivalents with updated suffixes. Consult ABLIC documentation for direct pin-compatible replacements that maintain the 3.5V output and 600kHz operation without requiring schematic changes.
