DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when ordering. Confirm the IDDB variant corresponds to the 8-WFDFN (3x2) package. Ensure compatibility with the required operating temperature range of -40°C to 125°C TJ. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm RoHS3 compliance status before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a non-synchronous controller for boost, flyback, or SEPIC topologies. It is suitable for driving external N-channel MOSFETs in high voltage scenarios. Consider the 240kHz fixed frequency and 78% max duty cycle when designing the power stage. Verify that the 4.1V to 60V supply range meets the system requirements.
