Overview
The AS1341-BTDT-6K is a synchronous step-down DC-DC converter manufactured by ams OSRAM. It provides an adjustable output or a fixed 5V option with a maximum output current of 600mA. The device operates from an input voltage range up to 20V and integrates high-side and low-side power switches for efficient conversion. It features a compact 8-TDFN package, suitable for space-constrained applications requiring stable regulated power.
Feature Summary
- Synchronous rectification architecture for enhanced efficiency
- Wide input voltage capability supporting up to 20V sources
- Integrated power switches eliminating external component requirements
- Compact surface-mount packaging for dense board layouts
Applications
- Portable electronic devices requiring efficient power regulation
- Battery-powered systems needing step-down conversion
- Embedded control circuits in consumer electronics
- Industrial sensor nodes with varying input voltages
Procurement Notes
Verify the specific output configuration (adjustable vs. fixed 5V) against the datasheet revision, as suffixes may indicate variant differences. Confirm the 8-TDFN package dimensions match your PCB footprint. Ensure thermal management strategies align with the 600mA load capabilities under expected ambient conditions. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a wide input voltage range up to 20V is required alongside moderate output current needs. The synchronous design offers better efficiency than non-synchronous alternatives at similar current levels. Consider the 8-TDFN package size if board real estate is limited. Verify that the desired output voltage matches the fixed 5V variant or adjustability requirements of the adjustable version.
Part Context
This part belongs to the AS1341 series of buck converters from ams OSRAM. The series focuses on providing reliable DC-DC conversion in small footprints. The BTDT suffix typically denotes the tape and reel packaging format. The 6K suffix often indicates a specific output voltage configuration or batch code within the manufacturer's coding system.
Replacement Considerations
Direct substitutes include other 20V input synchronous buck converters with 600mA output in TDFN packages. Check pin compatibility and thermal performance before swapping. Alternative parts must support the same input voltage range and offer comparable efficiency curves.
