The LTM4630-1A/LTM4630-1B are dual 18A or single 36A output step-down μModule® (power module) regulators with ±0.8% (LTM4630-1A) and ±1.5% (LTM4630-1B) total DC output error, respectively, with ±3% transient output error. Included in the package are the switching controller, power FETs, inductors, and all supporting components. External compensation allows for fast transient response to minimize output capacitance when powering FPGAs, ASICs, and processors. With synchronized multiphase parallel current sharing, four LTM4630-1 devices can deliver up to 144A. The LTM4630-1 is offered in a 16mm × 16mm × 5.01 BGA package. Features Vout LTM4630   0.6V to 1.8V LTM4630-1 0.8% DC and 3% Transient Accuracy 0.6V to 1.8V LTM4630A Higher Light Load Efficiency 0.6V to 5.3V

LTM4630-1 Dual 18A or Single 36A µModule® Regulator with ±0.8% DC and 3% Transient Accuracy Demonstration circuit 2157A features the LTM®4630EY-1, the high efficiency, high density, dual 18A, switch mode step-down power module regulator with ±0.8% total DC output accuracy. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 1.8V. DC2157A can deliver up to 18A maximum in each channel. With the help of external compensation, ±3% transient accuracy can be achieved with 25% load step. 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 36A 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 LTM4630-1 in a compact 16mm × 16mm × 5.01mm BGA package make it ideal for use in many high density point-of-load regulation applications. The LTM4630-1 data sheet must be read in conjunction with this demo manual for working on or modifying the demo circuit DC2157A.
