Maxim VT1697SBFQX

Полумост1,71 В ~ 1,98 В

Overview

The VT1697SBFQX is a feature-rich smart slave IC designed to work with Maxim’s seventh-generation masters to implement a highdensity 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 via SMBus/PMBus. 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. Monolithic integration and advanced packaging technologies allow practical per-phase, high switching frequencies with significantly lower losses than alternative implementations. Smart slave devices are 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. The VT1697SBFQX is packaged in a QFN package with exposed topside thermal pads. Top-side cooling allows improved heat transfer to ambient and reduces PC board and component temperatures.
