... OPERATION Power Module Description The LTM4606 is a standalone non-isolated switching mode DC/DC power supply. It can deliver output current with some external input and output capacitors. This module provides precisely regulated output voltage programmable via one external resistor from 0.6V 5.0V over a 4.5V to 28V input voltage range. The typical DC application schematic is shown in Figure 20 ...
