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.
