DC1083A-A (LINEAR TECHNOLOGY)

The DC1083A-A demonstration board features LTM4603 high efficiency, high density µModule regulator. The LTM4603 is a complete 6A step down switch mode DC to DC µModule regulator with onboard switching controller, MOSFETs, inductor and all support components. The low profile (2.82mm) and light weight (1.7g) package easily mounts on the unused space on the back side of PC boards for high density point of load regulation. The input voltage range is from 4.5V to 20V. The output voltage is jumper programmable from 0.6V to 5V. The rated load current is 6A, while derating is necessary for certain VIN, VOUT and thermal conditions. Applying an external clock signal to the PLLIN pin forces the µModule regulator to operate at the same frequency. The output ramp up and ramp down may be programmed through the TRACK/SS pin. Margining function is provided for the user who wants to stress their system by varying supply voltages during testing.
