VT1697SB
Description
The VT1697SB is a feature
-rich smart slave IC designed to work with Maxim’s seventh-generation masters to implement a high-density multiphase voltage regulator. Up to six smart slave ICs plus a master IC provide a pact synchronous buck converter that includes accurate individual phase current and temperature reporting through SMBus. This smart-slave device includes protection circuits for overtemperature, VX short, all power supplies UVLO faults, and main power supply OVLO fault. If a fault is detected, the slave IC immediately shuts down and sends a fault signal to the master IC.
Monolithic integration and advanced packaging technologies allow practical per-phase high switching frequencies with significantly lower losses than alternative implementations. This smart slave device is designed to support phase shedding and DCM modes for efficiency optimization over a wide range of load currents. High per-phase current capability designs with low COUT enable a design with...
