Overview
The AS1330-BTDT-18 is a synchronous boost switching regulator IC manufactured by ams OSRAM AG. It provides a fixed positive output voltage of 1.8V with a maximum switch current capability of 650mA. The device operates within an input voltage range up to 3V and integrates a 4MHz switching frequency. It is housed in an 8-UFDFN package with exposed pad for surface mount installation. The component supports operation across a temperature range of -40°C to +85°C ambient.
Feature Summary
- Synchronous rectification for improved efficiency
- Fixed positive output voltage configuration
- Integrated overcurrent protection
Applications
- Portable electronic devices requiring step-up power conversion
- Battery-powered systems needing stable 1.8V rails
- Consumer electronics with limited input voltage sources
Procurement Notes
Verify the exact suffix BTDT against official datasheets to confirm pinout and thermal characteristics. Confirm availability status as components may be discontinued. Ensure compatibility with existing PCB footprint and thermal management requirements before integration.
Selection Notes
Select this component when a fixed 1.8V output is required from a low-voltage source. Consider the 650mA current limit and 4MHz frequency for size constraints. Evaluate thermal performance in the 8-UFDFN package under expected load conditions.
Part Context
This part belongs to the AS1330 series of synchronous boost regulators from ams OSRAM. It is designed for space-constrained applications requiring efficient voltage step-up. The series typically offers integrated switches and control logic for compact designs.
Replacement Considerations
Check for direct pin-compatible alternatives from the same manufacturer or other suppliers offering similar boost topologies. Verify electrical parameters such as output voltage, current rating, and package dimensions match exactly.
