constant-current (CVCC) step-down μModule® regulator.  
Includedinthepackagearetheswitchingcontroller,power  
switches, inductor and support components. Operating  
over an input voltage range of 6V to 36V, the LTM8052  
supports an output voltage range of 1.2V to 24V. The  
LTM8052 is able to sink or source current to maintain  
voltage regulation up to the positive and negative current  
limits. This output current limit can be set by a control  
voltage, a single resistor or a thermistor.
