DC1743A

The DC1743A demonstration board features LTM4613EV DC to DC µModule regulator. The LTM4613EV is a complete, ultralow noise, 8A switch mode DC to DC power supply. Included in the IC package are the switching controller, power FETs, inductor and all support components. The input voltage range is from 5V to 36V. The output voltage is jumper programmable from 3.3V to 12V with a rated load current of 8A. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. Only input and output capacitors are needed externally. The DC1743A offers the TRACK/SS pin allowing the user to program output tracking or soft start period. Output voltage margining can also be realized through jumper position selections. Higher efficiency at low load currents is achieved by setting the MODE pin jumper to DCM. The PLL pin is available to synchronize the LTM4613EV to an external clock.
