What should engineers review before using LMR51635XFDDCR?

Verify the 4.3 V to 60 V input range, 0.8 V to 30 V adjustable output requirement, inductor saturation and RMS-current ratings, output-capacitor transient performance, and PCB thermal layout. EN must not float, and a 100 nF bootstrap capacitor is required between CB and SW.

What is the pinout of LMR51635XFDDCR?

Use the LMR51635XFDDCR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about LMR51635XFDDCR pinout to locate pins, power rails, and interface signals before layout.

AI summary

LMR51635XFDDCR is a 3.5 A, 400 kHz forced-PWM synchronous buck regulator for converting 4.3 V to 60 V inputs to an adjustable 0.8 V to 30 V output.

Best for

Wide-input industrial buck supplies
PLC, DCS, and PAC power rails
Applications requiring fixed-frequency forced PWM

Avoid if

A load current above 3.5 A is required
Light-load pulse-frequency modulation is required for highest efficiency
Input voltage can exceed 60 V

Check before use

Select the output feedback divider for the required output voltage
Check inductor peak-current margin against the current limit
Use a compact VIN-to-GND bypass loop and adequate copper for heat dissipation
