DC DC Switching Controllers Procurement Notes

Verify the specific ordering suffix 'R' indicates reel packaging when sourcing components. Confirm that the SOIC-Narrow-16 package dimensions match the target PCB footprint requirements. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the datasheet version to confirm compatibility with existing design specifications.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring precise phase interleaving to reduce input ripple. The 2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 10 mA drive strength for gate driver selection. Evaluate the thermal management needs given the 105°C maximum rating and narrow package form factor.
