LTM4630A overview
LTM4630A is a component documented by Linear Technology. The PDF description identifies it as "Dual 18A or Single 36A DC/DC 關Module Regulator." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

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 from an input voltage range of 4.5V to 18V, the LTM4630A supports two outputs each with an output voltage range of 0.6V to 8V, each set by a single external resistor .
- Its high efficiency design delivers up to 18A continuous current for each output.
- The LTM4630A is pin compatible with the LTM4620 and LTM4620A (dual 13A, single 26A) and the LTM4630 (dual 18A, single 36A).
- The device supports frequency synchronization, multi phase operation, Burst Mode operation and output voltage tracking for supply rail sequencing and has an onboard temperature diode for device temperature monitoring.
- High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
- The LTM4630A is offered in 16mm × 16mm × 4.41mm LGA and 16mm × 16mm × 5.01mm BGA packages.
- n Dual 18A or Single 36A Output n Input Voltage Range: 4.5V to 18V (after date code 1720*) n Output Voltage Range: 0.6V to 8V (after date code 1720*) n ±1.5% Maximum Total DC Output Error Over Line, Load and Temperature n Higher Light Load.

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.
