LTM4630EY-1 Demo Board | 3 Paralleled Buck µModules, 4.5V ≤ VIN ≤ 15V, VOUT = 0.9V to 1.8V @ 105A

Product Detail

Demonstration Circuit 2164A-B features a PolyPhase design using three LTM4630EY-1's (A-grade), the high efficiency, high density, dual 18A, switch mode step-down power module regulator. The input voltage is from 4.5V to 15V. The output voltage is jumper selectable and can be set to 0.9V, 1.0V, 1.2V, 1.5V or 1.8V. DC2164A-B can deliver nominal 105A output current. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions. The LTM4630-1A on DC2164A-B always operate in continuous conduction mode. The switching frequency can be programmed through a resistor or can be synchronized to an external clock signal. The board allows the user to program how its output voltage ramps up and down through the TRACK pin.

Product Detail

Demonstration circuit 2268A-E is a high efficiency, high density, dual 18A, switch mode step-down power supply on a compact 1.5' × 1.2' PCB. It features the LTM4630-1 μModule regulator. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 1.8V. DC2268A-E 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 resistor jumper (R1/R2) selects pulse-skipping mode for noise sensitive applications or Burst Mode® in less noise sensitive applications. Two outputs can be connected in parallel for a single 36A output solution with optional jumper resistors.
