Summary
Demonstration circuit DC1084A-B features the LTM®4602HV, the high efficiency, high density step-down μModule® regulator. The input voltage range is from 4.5V to 28V.
The output voltage is jumper programmable from 0.6V to 5V, refer to the step-down ratio curve in the LTM4602HV data sheet. The rated load current is 6A, while derating is necessary for certain VIN, VOUT and thermal conditions.
