AS1345A-BTDT-AD

Overview

The AS1345A-BTDT-AD is a boost switching regulator IC manufactured by ams-OSRAM USA INC. It provides a single positive adjustable output capable of delivering up to 1A of switch current. The device operates as a high-efficiency DC/DC step-up converter, designed for applications requiring voltage elevation from lower input sources. It is housed in an 8-TDFN package with an exposed pad, suitable for surface-mount assembly.

Feature Summary

• High-efficiency step-up conversion topology
• Adjustable positive output voltage configuration
• Integrated synchronous rectification for improved performance

Applications

• Battery-powered portable electronics
• Low-voltage input systems requiring higher output rails
• General-purpose DC/DC step-up power supplies

Procurement Notes

Verify the specific suffix and manufacturer designation when sourcing. Confirm package type and pinout compatibility with existing board layouts. Check for obsolescence status or alternative recommendations from the manufacturer. Ensure supply chain authenticity through authorized channels.

Selection Notes

Select this component when a compact boost solution is needed for currents up to 1A. Consider the adjustable output range and operating frequency requirements against system constraints. Evaluate thermal performance given the TDFN package limitations in high-current scenarios.

Part Context

This part belongs to the ams-OSRAM PMIC portfolio, specifically within the DC-DC switching regulator category. It complements other buck and boost converters in the series, offering a specialized step-up function for power management designs requiring efficient voltage translation from low-voltage sources.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family. Verify electrical parameter equivalence for input/output ranges and current limits. Consult manufacturer cross-reference guides for updated components if this part is discontinued.
