- Telecommunications infrastructure power supplies
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and material declarations prior to integration. Note that availability may be restricted due to supply constraints; check current stock levels and lead times carefully before finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring wide input voltage ranges and bidirectional power flow capabilities. Ensure the thermal design accommodates the SOIC package limitations under high load conditions. Verify that the required output voltage falls within the 1.244V to 60V adjustable range and that the 4A switch current meets the system's peak demand requirements.
Part Context
This part belongs to the LT1269 series of power management integrated circuits from Analog Devices. It is specifically engineered as a versatile DC-DC converter solution suitable for applications demanding high efficiency and flexible topology options. The CSW suffix indicates the commercial temperature grade and the specific 20-SOIC package variant.
Replacement Considerations
Consult official Analog Devices documentation for verified cross-reference part numbers. Ensure any substitute component matches the 20-SOIC footprint, 100kHz switching frequency, and 4A current handling capability. Validate pin compatibility and control interface specifications before implementation.
