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, VOUT OVF/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.
