Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- The LTM4636 can deliver 40W (12VIN, 1VOUT, 40A, 200LFM) with only 40°C rise over the ambient temperature.
- Full-power 40W is delivered, up to 83°C ambient and half-power 20W is supported at 110°C ambient.
- The LTM4636 operates at 92%, 90% and 88% efficiency, delivering 15A, 30A and 40A, respectively, to a 1V load (12VIN).
- The µModule regulator is scalable such that four µModules in current sharing mode deliver 160W with only 40°C rise and 88% efficiency (12V IN, 1VOUT, 400LFM).
- The LTM4636 is offered in a 16mm × 16mm × 7.07mm BGA package.

Engineering review checklist
- Verify supply range, input common-mode range and output swing at the required load.
- Check offset, bias current, noise, bandwidth, slew rate and stability for the intended feedback network.
- Review supply decoupling, source impedance, capacitive-load behavior and thermal limits in the final layout.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
