Overview
The AS1341-BTDM is a synchronous buck switching voltage regulator manufactured by ams OSRAM. It operates with an input voltage range of 4.5 V to 20 V and delivers a maximum output current of 600 mA. The device supports adjustable output voltages from 1.25 V to 20 V, with a fixed 5 V option available. It functions at a switching frequency of 200 kHz and is housed in a TDFN-8 surface-mount package. The component is rated for operation between -40°C and +85°C.
Feature Summary
- Synchronous buck topology for efficient DC-DC conversion
- Integrated power switch for compact design
- Adjustable output voltage capability within specified limits
Applications
- Portable electronic devices requiring regulated power
- Embedded systems utilizing low-voltage logic
- Battery-powered equipment needing step-down regulation
Procurement Notes
Verify the End-of-Life status prior to procurement planning. The AS1341-BTDM is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets if immediate replacement is required. Ensure that any sourced units match the original datasheet specifications to maintain system compatibility and performance reliability.
Selection Notes
Select this component when a synchronous buck converter with a 600 mA output capacity is required. Consider the 200 kHz switching frequency for EMI management and external component sizing. Evaluate the TDFN-8 package constraints against PCB layout requirements. Verify that the input voltage range aligns with the system supply rails and that the thermal performance meets the operating temperature conditions.
Part Context
The AS1341 belongs to the AS1341 series of PMICs from ams OSRAM. This series focuses on power management integrated circuits designed for mobile and portable applications. The BTDM suffix indicates specific packaging and tape-and-reel configuration details consistent with the manufacturer's standard ordering nomenclature for this product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative components must be selected based on functional equivalence, including input/output voltage ranges, current ratings, and package dimensions.
