Procurement Notes
Verify the exact part number suffix against official ams OSRAM documentation to confirm pinout and electrical specifications. Ensure compatibility with your PCB footprint and thermal design requirements. Check for end-of-life status or alternative recommendations directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a compact, high-current synchronous buck solution is required. The adjustable output allows flexibility for various rail voltages. Consider the 1MHz switching frequency for smaller external passive components compared to lower-frequency alternatives. Verify input voltage ranges match the system power source.
Part Context
The AS1335 series belongs to ams OSRAM's portfolio of power management integrated circuits. These devices are designed for applications requiring efficient power conversion from higher battery voltages to lower logic levels. The BTDT suffix indicates the specific tape-and-reel packaging format and temperature grade.
Replacement Considerations
Consult official ams OSRAM substitution guides for verified equivalents. Generic replacements may differ in pinout, thermal performance, or control loop characteristics. Validate any substitute against the original datasheet parameters.
