cromodule) converter. Included in the package are the  
switching controller, power switches, inductor and all  
support components. Operating over an input voltage  
range of 3.6V to 58V, the LTM8050 supports an output  
voltage range of 0.8V to 24V and a switching frequency  
range of 100kHz to 2.4MHz, each set by a single resistor.  
Only the bulk input and output filter capacitors are needed  
to finish the design.
