Demonstration circuit 2268A-I is a high efficiency, high density, dual 8A, switch mode step-down power supply on a compact 1.5' × 1.2' PCB. It features the LTM4650A-1 μModule® regulator. The input voltage is from 4.5V to 16V. The output voltage is programmable from 0.6V to 5.3V. DC2268A-I can deliver up to 25A maximum in each channel. 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 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. Remote output voltage sensing is available for improved output voltage regulation at the load point. An optional input inductor L1 reduces the EMI noise for noise sensitive applications. DC2268A can be easily inserted to an edge connector for testing and debugging. These features and the availability of the LTM4650A-1 in a compact 16mm × 16mm × 4.41mm LGA package make it ideal for use in many high-density point-of-load regulation applications.

This tracking scheme, along with internal boost regulator frequency compensation and integrated Schottky diodes, minimizes external component count and simplifies system design. Each linear regulator includes internal current limit and thermal limit protection circuitry.The LT3095 switching frequency is externally programmable with a single resistor from 450kHz to 2MHz. A SYNC pin allows synchronization to an external clock.
