Description
Demonstration circuit 2440A is an 8-output power supplyfeaturing the LTC®3374A with improved efficiency and accuracycompared to the LTC3374. The LTC3374A has eightsynchronous buck regulators each with an independentVIN supply. Up to four buck regulators may be paralleledtogether to create a higher power buck regulator with asingle inductor. The input range of the LTC3374A is idealfor single cell Li-Ion/Polymer battery applications.
