The TPS544E27 device is highly integrated buck converter with D-CAP+ control topology for fast transient response. All programmable parameters can be configured by the PMBus interface and stored in non-volatile memory (NVM) as the new default values to minimize the external component count. These features make the device well-designed for space-constrained applications.

The TPS544E27 device is designed to work with Intel CPUs and fits well for single-phase, low-to-mid current SVID rails in the Intel server and SoC platforms requiring VR13, VR14, or VR14.Cloud compliance.

Fault management and status reports for the overcurrent fault (OCF), VOUT overvoltage fault (OVF), undervoltage fault (UVF), and overtemperature fault are provided on the device. The TPS544E27 device provides a full set of telemetry, including output voltage, output current, and device temperature. Additionally, input power monitoring through an external sensing resistor is provided for board-level power management.

TPS544E27 is a lead-free device and is RoHS compliant without exemption.
