DESCRIPTION
Demonstration circuit DC823B-A features the
LTM
4600EV, a 10A high efficiency, high density switch
®
mode step-down power module. The input voltage is from
4.5V to 20V. The output voltage is programmable from
0.6V to 5V. The rated load current is 10A, while derating is
necessary for different V
Integrated input and output filters enable a simple PCB
layout. Only bulk input and output capacitors are needed.
