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.
- Operating over an input voltage range from 4.5V to 20V, the LTM4637 supports an output voltage range of 0.6V to 5.5V, set by a single external resistor.
- Current mode operation allows precision current sharing of up to four LTM4637 regulators to obtain up to 80A output .
- High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
- The device supports frequency synchronization, multiphase/current sharing, Burst Mode operation and output voltage tracking for supply rail sequencing.
- The LTM4637 is offered in a 15mm × 15mm × 4.32mm LGA package.
- The LTM4637 is pin compatible with the LTM4627, a 15A DC/DC µModule regulator.

Engineering review checklist
- Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
- Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
- Review package thermal resistance, copper area, polarity marking and transient derating before layout release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
