Maxim Integrated VT1697SB
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. This smart-slave device includes protection circuits for overtemperature, VX short, all power supplies UVLO faults, and main power supply OVLO fault. The VT1697SB is an FCQFN package with exposed topside thermal pads.GENERAL DESCRIPTION
Up to six smart slave ICs plus a master IC provide a compact synchronous buck converter that includes accurate individual phase current and temperature reporting through SMBus. 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 fewer phases and a smaller footprint. Top-side cooling allows improved heat transfer to ambient and reduces PC board and component temperatures.APPLICATIONS
