The LTC3546, a dual output current mode buck regulator with flexible output current partitioning, is described.
Dual output buck regulator
The LTC3546 is a dual output current mode buck regulator with flexible output current partitioning. Beyond the advantages normally associated with dual output regulators (reduced size, cost, EMI and part count, with improved efficiency), the LTC3546’s outputs can be partitioned for either 3A and 1A outputs, or two 2A outputs. This increases its application range and simplifies multiple supply rail designs. ...
