Overview
The AS1334-BTDT-30 is a synchronous buck switching regulator IC manufactured by ams OSRAM. It provides a fixed positive output voltage of 3V with a maximum output current capability of 650mA. The device operates within an input voltage range up to 5.5V and utilizes a 2MHz switching frequency for efficient power conversion. Designed for surface-mount installation, it is housed in an 8-WDFN package with an exposed pad to facilitate thermal management. The component supports operation across a wide ambient temperature range from -40°C to +85°C.
Feature Summary
- Synchronous rectification architecture for enhanced efficiency
- Fixed 3V output configuration
- Compact 8-WDFN exposed pad packaging
Applications
- Battery-powered portable electronics
- Smart personal care devices
- Consumer home appliances
Procurement Notes
Verify the obsolete lifecycle status before procurement planning. Confirm the 8-WDFN package compatibility with existing PCB footprints. Ensure thermal design accounts for the exposed pad requirements. Check for authorized distribution channels as standard stock may be limited due to end-of-life status.
Selection Notes
Select this component when a fixed 3V rail is required from a single-cell lithium battery source. The 650mA limit suits low-power applications. The 2MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 5.5V maximum input rating aligns with the system's supply voltage peaks.
Part Context
This part belongs to the AS133x series of DC-DC converters from ams OSRAM. These regulators are designed for space-constrained applications requiring high efficiency. The series typically includes variants with different output voltages and current ratings, sharing similar control logic and package styles for design flexibility.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements should be verified against specific electrical parameter matches and thermal characteristics.
