• Point-of-load regulation

Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm RoHS compliance and moisture sensitivity handling requirements before assembly. Check for recent Product Change Notifications or discontinuance notices from the manufacturer to ensure long-term availability and specification consistency.

Selection Notes

Select this controller for designs requiring a 300 kHz fixed frequency synchronous buck solution. Ensure the application demands support for up to 25 A output current and operation down to 600 mV. Verify that the LFCSP-14 package fits the PCB layout constraints and thermal management strategy.

Part Context

This part belongs to the ADP187x series of synchronous buck controllers from Analog Devices. It shares architectural similarities with models like the ADP1870 and ADP1871 but differs in specific pinout configurations and package types such as the LFCSP-14 used here.

Replacement Considerations

Direct substitutes include ADP1870ACPZ-0.3-R7 and ADP1871ACPZ-0.3-R7. Verify pin compatibility and package differences before substitution.
