DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the QFN-28 package thermal pad connection is properly designed for heat dissipation during high-load operations.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring two isolated or synchronized low-voltage outputs from a higher bus voltage. Evaluate the maximum load current requirements against the external MOSFET selection rather than internal limits. Consider the operating temperature range and ensure adequate PCB layout space for the QFN-28 footprint.
