What is LM60440ARPKR used for?

It is intended for compact industrial DC/DC rails, including industrial PCs and CPU rails, PLC controllers, servo and AC-drive control modules, and medical equipment.

What should engineers review before using LM60440ARPKR?

Keep the VIN-PGND input bypass loop short and wide, place the 100 nF bootstrap capacitor close to BOOT and SW, use a 1 µF VCC capacitor, and verify inductor saturation current, output capacitance under DC bias, thermal performance, and conducted EMI.

What is the pinout of LM60440ARPKR?

Use the LM60440ARPKR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about LM60440ARPKR pinout to locate pins, power rails, and interface signals before layout.

AI summary

LM60440ARPKR is a 400 kHz, 4 A synchronous buck regulator for converting 3.8 V to 36 V inputs to adjustable 1 V to 24 V outputs.

Best for

Industrial step-down rails up to 4 A
Applications requiring 36 V input capability
Compact 400 kHz synchronous buck designs

Avoid if

A fixed switching frequency is required at light load
The required load current exceeds 4 A
Validated production data rather than Advance Information is mandatory

Check before use

Confirm actual capacitor derating and loop stability
Verify thermal margin using the final PCB copper and vias
Check input transients do not exceed 38 V absolute maximum
