3 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.
