DESCRIPTION
LTM4600:
20V, 10A Step-Down Power
µModule
®
Regulator
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
IN
, V
OUT
, and thermal conditions.
Integrated input and output filters enable a simple PCB
layout. Only bulk input and output capacitors are needed.
