DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the EMSE designation corresponds to the commercial temperature grade (-40°C to +85°C) required for the application environment. Ensure compatibility with the 10-lead MSOP footprint and verify RoHS compliance status through official manufacturer documentation prior to procurement.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring flexible topology support including flyback, boost, or SEPIC configurations. The adjustable frequency feature allows optimization for size and efficiency trade-offs. Consider the 360 uA quiescent current for standby power requirements. Verify that the input voltage range aligns with the internal shunt regulator capabilities and that the output voltage specifications meet the load requirements.
