DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape and reel packaging specifications. Ensure compatibility with the required operating temperature range and confirm that the component meets RoHS3 standards before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when driving N-channel GaN FETs in high-voltage environments requiring low quiescent current. It is suitable for designs needing precise driver voltage adjustment and flexible frequency synchronization without additional external clamping components.

DC DC Switching Controllers Part Context

This component belongs to the LTC7890/LTC7891 family of synchronous buck controllers. While the LTC7890 offers dual channels in a larger package, the LTC7891 provides a single-channel solution in a compact footprint, both targeting high-efficiency power conversion using advanced GaN technology.
