DC DC Switching Controllers Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm pinout and electrical characteristics. Ensure the SSOP-28 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement specifications.
DC DC Switching Controllers Selection Notes
Select this component when designing systems requiring two synchronized buck converters from a single wide-input voltage source. The fixed 220kHz frequency allows for optimized passive component sizing. Consider thermal management requirements associated with the SSOP-28 package for continuous load applications.
DC DC Switching Controllers Part Context
This part belongs to the PolyPhase series of power management ICs from Analog Devices. It serves as a dedicated controller rather than an integrated switch, requiring external power stages. The design targets applications needing precise phase alignment between multiple output voltages.
