n Available in a 28-Pin (4mm × 5mm) QFN Package The LTC®3870 is a PolyPhase® step-down slave controller specially designed for multiphase operation with the
LTC3880 family digital power system management DC/DC
controllers. It provides a small and cost effective solution
for supplying very large currents by cascading it with a
master controller. A peak current mode architecture provides the LTC3870 with excellent current sharing from …
