4V to 18V input, 40A, PMBus and SVID synchronous step-down converter

The TPS544E27 is a

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.
