What should engineers review before using LMR51625XDDCR?

Confirm that the 4.3 V to 60 V input range covers both steady-state and transient input conditions. Set the feedback divider for the required 0.8 V to 30 V output, select an inductor with sufficient saturation-current margin, use a 0.1 µF CB-to-SW bootstrap capacitor, and follow the recommended high-current PCB layout.

What is the pinout of LMR51625XDDCR?

Use the LMR51625XDDCR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about LMR51625XDDCR pinout to locate pins, power rails, and interface signals before layout.
