constant-voltage, constant-current (CVCC) step-down  
μModule® regulator. Included in the package are the  
switchingcontroller,powerswitches,inductorandsupport  
components.Operatingoveraninputvoltagerangeof6Vto  
36V, theLTM8052/LTM8052Asupportsanoutputvoltage  
range of 1.2V to 24V. The LTM8052/LTM8052A is able to  
sink or source current to maintain voltage regulation up to  
thepositiveandnegativecurrentlimits.Thisoutputcurrent  
limit can be set by a control voltage, a single resistor or a  
thermistor. LTM8052featuresa125%outputovervoltage  
protection, while LTM8052A does not, allowing operation  
when the output is above the target regulation point.
