Demonstration circuit 2268A-F 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 LTM4630A μModule® regulator. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 5.3V. DC2268A-F can deliver up to 18A 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 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. 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 LTM4630A in a compact 16mm × 16mm × 4.41mm LGA package make it ideal for use in many high-density point-of-load regulation applications. The LTM4630A data sheet must be read in conjunction with this demo manual for working on or modifying the DC2268A-F.

The LT8331 is a current mode DC/DC converter with a 140V, 0.5A switch operating from a 4.5V to 100V input. With a unique single feedback pin architecture, it is capable of boost, SEPIC, flyback or inverting configurations. Burst Mode operation consumes as low as 6?A quiescent current to maintain high efficiency at very low output currents, while keeping typical output ripple below 20mV.The internally-compensated current mode architecture results in stable operation over a wide range of input and output voltages and programmable switching frequencies between 100kHz to 500kHz. A SYNC/MODE pin allows synchronization to an external clock. It can also be used to select between burst or pulse-skipping modes of operation. For increased efficiency, a BIAS pin can accept a second input to supply the INTVCC regulator. Additional features include frequency foldback and programmable soft-start for controlling inductor current during start-up.The LT8331 is available in a thermally-enhanced MSOP package with four pins removed for high voltage spacings.Applications Industrial and Automotive Telecom Medical Diagnostic Equipment Portable Electronics
