Overview
The AS1331-BTDT-AD is a synchronous buck-boost switching regulator IC manufactured by ams OSRAM. It provides a fixed positive output voltage of 2.5V with a maximum switch current of 450mA. The device operates within an input voltage range of 1.8V to 6V and supports both step-up and step-down conversion topologies. It features a switching frequency of 500kHz and is housed in a 10-WFDFN exposed pad package. The component functions as a DC/DC converter capable of handling input voltages above, below, or equal to the output voltage.
Feature Summary
- Synchronous buck-boost topology for flexible voltage regulation
- Integrated power switch supporting up to 450mA load current
- Fixed 2.5V output configuration for stable supply rails
Applications
- Portable battery-powered devices requiring voltage stabilization
- Systems with varying input voltage sources relative to output requirements
- Embedded electronics needing compact DC/DC conversion solutions
Procurement Notes
Verify part status carefully as this specific variant may be obsolete or discontinued. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints and thermal management designs. Check for alternative revisions or updated series components if production continuity is required. Validate datasheet specifications against current application needs before procurement.
Selection Notes
Select this component when a fixed 2.5V output is required from a variable input source between 1.8V and 6V. Consider the 10-TDFN package size for space-constrained designs. Evaluate the 450mA current limit against peak load demands. Compare efficiency characteristics at specific operating points against other buck-boost regulators in the same family.
Part Context
This part belongs to the AS1331 series of synchronous buck-boost converters. It shares functional similarities with variants like AS1331-BTDT-30 and AS1331-BTDT-33, which offer different fixed output voltages. The series is designed for low-power applications requiring efficient energy management from single-cell lithium-ion batteries or similar power sources.
Replacement Considerations
Direct substitutes include AS1331-BTDT-30 (3.0V output) and AS1331-BTDT-33 (3.3V output) if voltage levels can be adjusted. Other compatible parts in the AS1331 family may serve as alternatives depending on specific output voltage requirements and current capabilities.
