Overview
The AS1311-BTDT is a synchronous boost switching regulator IC manufactured by ams-OSRAM. It provides a fixed positive output voltage of 1.8V with a maximum switch current capability of 320mA. The device operates within an input voltage range up to 3V and features a switching frequency of 4MHz. It is housed in an 8-lead UFDFN package with exposed pad, designed for surface-mount installation. The component supports operation across a temperature range of -40°C to +85°C.
Feature Summary
- Synchronous rectification topology for improved efficiency
- Fixed 1.8V output configuration
- Compact 8-lead UFDFN surface-mount package
Applications
- Portable electronic devices requiring step-up power conversion
- Battery-powered systems needing stable 1.8V rails
- Mobile communication modules
Procurement Notes
Verify the specific suffix BTDT against official datasheets to confirm pinout and thermal characteristics. Confirm availability status as distribution channels may list obsolete or discontinued stock. Ensure compatibility with existing PCB footprint designs before procurement.
Selection Notes
Select this component when a fixed 1.8V output is required from a low-voltage source. Consider the 320mA current limit and 4MHz switching frequency for noise-sensitive applications. Evaluate the 8-UFDFN package constraints for thermal management and board space limitations.
Part Context
This part belongs to the AS13xx series of DC-DC converters from ams-OSRAM, focusing on compact power management solutions for mobile and wearable electronics. The series typically integrates synchronous rectifiers to maximize efficiency in small form factors.
Replacement Considerations
Check for direct cross-references in distributor databases. Verify equivalent electrical parameters such as output voltage, current rating, and package dimensions if substituting.
