DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific EG suffix denotes the extended industrial temperature grade (-40°C to +125°C) as per the official datasheet. Ensure the SSOP-28 package matches your PCB footprint requirements. Check for RoHS compliance status in the latest documentation before finalizing procurement specifications.

DC DC Switching Controllers Selection Notes

Select this controller when designing synchronous buck converters requiring high input voltage tolerance and moderate output current capabilities. The 250 kHz switching frequency offers a balance between efficiency and component size. Consider the 240 uA quiescent current for standby power constraints. Ensure external MOSFET selection aligns with the 10 A output requirement and thermal dissipation needs within the specified operating temperature range.
