The TPS53659 is a fully
VR13 SVID compliant step-down controller with dual channels,
built-in non-volatile memory (NVM), and PMBus™ interface, and is
fully compatible with TI NexFET™ power stage. Advanced control
features such as D-CAP+™ architecture with undershoot reduction
(USR) provide fast transient response, low output capacitance, and good current sharing. The device
also provides novel phase interleaving strategy and dynamic phase shedding for efficiency
improvement at different loads. Adjustable control of VCORE slew rate and
voltage positioning round out the Intel®
features. In addition, the device supports the PMBus communication interface for
reporting the telemetry of voltage, current, power, temperature, and fault conditions to the
systems. All programmable parameters can be configured by the PMBus interface and can be stored in
NVM as the new default values to minimize the external component count.
The TPS53659 device if offered in a thermally enhanced 40-pin WQFN
packaged and is rated to operate from –40°C to 125°C.
