Demonstration circuit DC823B-B features the LTM®4600HVEV, a 10A high efficiency, high density switch mode step-down power module.
The input voltage is from 4.5V to 28V.
The output voltage is programmable from 0.6V to 5V. The rated load current is 10A, while derating is necessary for different VIN, VOUT, and thermal conditions.
Integrated input and output filters enable a simple PCB layout.
Only bulk input and output capacitors are needed.
The LTM4600HV data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC823B-B.
