DC DC Switching Controllers Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence according to manufacturer documentation. Confirm the IUF designation corresponds to the industrial temperature grade (-40°C to +125°C) and QFN-24 package type. Ensure compatibility with external MOSFET selection based on the 25 A output current requirement and specified input voltage range.
DC DC Switching Controllers Selection Notes
Select this controller when a wide input voltage range up to 38 V is required for single-phase buck applications. The differential remote sensing feature makes it suitable for systems requiring precise voltage regulation at the load point. Consider the thermal performance of the QFN-24 package relative to the 25 A output current capability and ambient operating conditions.
