The LTM4650A is a dual 25A or single 50A output switching mode step-down DC/DC μModule® (micromodule) regulator with ±1% total DC output error. Included in the package are the switching controllers, power FETs, inductors and all supporting components. Operating from an input voltage range of 4.5V to 16V, the LTM4650A supports two outputs with an output voltage range of 0.6V to 5.5V, each set by a single external resistor. Its high efficiency design delivers up to 25A continuous current for each output. Only a few input and output capacitors are needed. Fast internal control loop compensation allows for fast transient response to minimize output capacitance when powering FPGAs, ASICs, and processors.

Fault protection features include overvoltage and overcurrent protection. The LTM4650A is offered in 16mm × 16mm × 5.01mm BGA package.

Product Detail

Demonstration circuit 2603A-A features the LTM4650AEY-1, the high efficiency, high density, dual 25A, single 50A switch mode step-down power module regulator. The input voltage is from 4.5V to 16V. The output voltage is programmable from 0.6V to 5.5V. DC2603A-A can deliver 25A maximum current from each channel. The board designs with minimum components to demonstrate this high efficiency, high density μModule®. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE jumper (JP1) selects pulse-skipping mode for noise sensitive applications or Burst Mode® operation in less noise sensitive applications. Two outputs can be connected in parallel for a single 50A output solution with optional jumper resistors. The board allows the user to program how its output ramps up and down through the TRACK/SS pin. The output can be set up to either coincidentally or ratiometrically track with another supply’s output. Remote output voltage sensing is available for improved output voltage regulation at the load point. These features and the availability of the LTM4650AEY in a compact 16mm × 16mm × 5.01mm BGA package make it ideal for use in many high-density point-of-load applications. The LTM4650A data sheet must be read in conjunction with this demo manual for working on or modifying the demo circuit DC2603A-A.
