Analog Devices / Maxim Integrated VT1697SB Smart Slave IC

Analog Devices Inc. VT1697SB Smart Slave IC is designed to work with ADI's 7th-generation masters to utilize a high-density multiphase voltage regulator. 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. 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 will immediately shut down and send a fault signal to the master IC. The ADI VT1697SB comes packaged in a QFN package with exposed top-side thermal pads. Top-side cooling allows improved heat transfer to ambient and reduces PC board and component temperatures.
