Description

The TPS544C26 device is a highly integrated buck converter with D-CAP+ control topology for the fast transient response. All programmable parameters can be configured by the I2C interface and stored in NVM as the new default values to minimize the external component count. These features make the device well-suited for space-constrained applications. The TPS544C26 device is designed to work with Intel CPUs and fits well for single-phase, low-to-mid current SVID rails in Intel’s server and SoC platforms. Fault management and status reports for the Overcurrent limit, VOUTOVF/UVF, and OTF are provided on the device. The TPS544C26 device provides a full set of telemetry, including VOUT, IOUT, and IC temperature. Additionally, input power monitoring through an external sensing resistor is provided for board-level power management. The TPS544C26 device is a lead-free device and is RoHS compliant without exemption.
