The LTC3870-1 is a PolyPhase® step-down slave controller specially designed for multiphase operation with LTC's 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 LTC3887-1 controller. A peak current mode architecture provides the LTC3870-1 with excellent current sharing from phase to phase and from chip to chip.
Coherently working with the LTC3887-1, the LTC3870-1 does not require additional I2C addresses, and it supports all programmable features as well as fault protection. The constant switching frequency can be synchronized to an external clock from the LTC3887-1 over a range of 100kHz to 1MHz.
