AS1340A-BUWB

Overview

The AS1340A-BUWB is a boost converter from ams-OSRAM USA INC. It features an internal 1.4A switch housed in a TDFN-8 3x3mm package. The device operates from a 2.7 to 5.5V input voltage range. It provides an adjustable output voltage capability with a maximum current rating of 1.41A.

Feature Summary

• Integrates a high-current internal power switch for efficient energy conversion
• Utilizes a compact surface-mount package design suitable for space-constrained layouts

Applications

• Portable electronic devices requiring step-up voltage regulation
• Battery-powered systems needing stable boosted output voltages
• General-purpose DC-DC conversion in compact consumer electronics

Procurement Notes

Verify the specific suffix BUWB against official datasheets to confirm pinout and thermal characteristics. Ensure compatibility with your PCB footprint, as the TDFN-8 package requires precise soldering techniques. Cross-reference manufacturer documentation for any revisions or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a compact boost regulator with moderate current capacity is required. The fixed 3x3mm package limits board space options. Consider thermal management requirements due to the internal switch configuration. Verify input voltage ranges align with your power source specifications.

Part Context

This part belongs to the AS1340 series of DC-DC switching regulators. It is designed for applications requiring efficient voltage boosting in small form factors. The series typically targets portable electronics where space and efficiency are critical constraints.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family. Verify that alternative components meet the 1.4A current and 5.5V input limits. Ensure package dimensions match the existing TDFN-8 footprint.
