Beschreibung

The EVAL-LTM4652-AZ evaluation board features the LTM®4652EY, source/sink dual ±25A or single ±50A output switching mode step-down DC-to-DC μModule® regulator. The input voltage is from 4.5V to 18V. The output voltage is programmable from 0.6V to 5V. The EVAL-LTM4652-AZ evaluation board can deliver 25A maximum current from each channel. As explained in the LTM4652 data sheet, the output current derating is necessary for certain VIN, VOUT, and thermal conditions. The EVAL-LTM4652-AZ evaluation board operates in continuous-conduction mode (CCM) in heavy load conditions. For high efficiency at low load currents, pulse-skipping mode (PSM) is selected with the MODE jumper (JP1) for noise-sensitive applications. Two outputs can be connected in parallel for a single 50A output solution with optional jumper resistors. The evaluation 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 compact size of the LTM4652, 16mm × 16mm × 4.92mm, BGA package, make it ideal for use in many high-density point-of-load (POL) regulation applications. The LTM4652 data sheet must be read in conjunction with this user guide for working on or modifying the EVAL-LTM4652-AZ evaluation board.
