The TPS40090RHDR from Texas Instruments is a high-frequency, multiphase buck controller optimized for low-voltage, high-current applications. It supports two-, three-, or four-phase operation, with this specific model featuring four phases. The device operates from an input voltage range of 5V to 15V and can deliver an output voltage from 0.7V to 3.5V.
Key features include current mode control with forced current sharing, a programmable switching frequency up to 1 MHz per phase, and a 1% internal 0.7V reference. It offers true remote sensing and supports resistive or DCR current sensing with fault protection. The controller is available in a 28-pin VQFN package, suitable for surface mounting.
This controller is designed for applications such as internet servers, network equipment, and telecommunications equipment, where efficient power delivery and fast transient response are critical. The multiphase architecture helps reduce input and output current ripple, improving overall system efficiency and power handling capabilities.
