The LTM4624 is a complete 4A step-down switching mode μModule® (micromodule) regulator in a tiny 6.25mm × 6.25mm × 5.01mm BGA package. Included in the package are the switching controller, power FETs, inductor and support components. Operating over an input voltage range of 4V to 14V or 2.375V to 14V with an external bias supply, the LTM4624 supports an output voltage range of 0.6V to 5.5V, set by a single external resistor. Its high efficiency design delivers 4A continuous, 5A peak, output current. Only bulk input and output capacitors are needed.

The LTM4624 supports selectable discontinuous mode operation and output voltage tracking for supply rail sequencing. Its high switching frequency and current mode control enable a very fast transient response to line and load changes without sacrificing stability.

Fault protection features include overvoltage, overcurrent and overtemperature protection.

The LTM4624 is available with SnPb (BGA) or RoHS compliant terminal finish.

Product Detail

Demonstration circuit 1889A features the LTM4624EY μModule regulator, a tiny high performance high efficiency step-down regulator. The LTM4624EY has an operating input voltage range of 4V to 14V and is able to provide an output current of up to 4A. The output voltage is programmable from 0.6V to 5V. The LTM4624EY is a complete DC-DC point of load regulator in a thermally enhanced 6.25mm × 6.25mm × 5.01mm BGA package requiring only a few input and output capacitors. Output voltage tracking is available through the TRACK/SS pin for supply rail sequencing. The LTM4624 datasheet must be read in conjunction with this demo manual for working on or modifying demo circuit 1889A.

Features and Benefits

  • Analog Devices has worked closely with Intel PSG to develop verified power solutions that optimize cost, size and efficiency in high performance applications.
  • The validated power solutions include uModules power products that address time and space constraints while delivering high efficiency, reliability, and low noise.
  • The actual power tree represents the best solution at time of design.
  • A recommended power tree has also been included to present the ideal solution at time of Stratix 10 GX SI development kit release. An updated alternate version of the power tree represents the latest solutions available from Analog Devices. For many applications, an intermediate rail is not ideal, so recommendations for an alternate power tree that allows for direct power conversion from 12V input is provided below.
