3 Description
The TPS536C9T is a VR14 SVID compliant step
down controller with trans-inductor voltage regulator
(TLVR) topology support, two channels, built-in nonvolatile
memory (NVM), and PMBus™ interface, and
is fully compatible with TI smart power stages.
Advanced control features such as the D-CAP+
architecture provide fast transient response, low
output capacitance, and good dynamic current
sharing. Adjustable control of output voltage slew
rate and adaptive voltage positioning are natively
supported. In addition, the device supports the PMBus
communication interface for reporting the telemetry
of voltage, current, power, temperature, and fault
conditions to the host system. All programmable
parameters can be configured through the PMBus
interface and can be stored in NVM as the new
default values, to minimize the external component
count.
