The TPS53679RSBR is a dual-channel, 6+1/5+2 VR13, D-CAP+™ Step-Down Multiphase Controller with Non-Volatile Memory (NVM) and PMBus manufactured by Texas Instruments. It is designed to manage power for high-end server, storage, networking, and other computing applications. It is a 40-WQFN package, operating at -40°C to 125°C and offers an optimum combination of power and thermal performance. Features include up to 95% efficiency, up to 770kHz switching frequency, low Rds(on), and external sense amplifiers for remote voltage sensing. The device also includes integrated power management unit (PMU) which allows for precise real-time power management and control. Additionally, the device includes overvoltage protect, over-temperature protection and soft-start. It also features advanced power sequencing output delay, voltage slew rate control, and OV/UV tracking. The PMBus interface allows for programming and reading of several parameters for improved system operation. The TPS53679RSBR is optimized for high current regulation with high resolution voltage sensing, tight regulation, fast transient response times, and output current sensing and compensation.
