The TPS53689 is a VR14 SVID compliant step down controller with two channels, built-in non-volatile memory (NVM), and PMBus™ interface, and is fully compatible with TI NexFET™ power stages. Advanced control features such as the D-CAP+ architecture with undershoot reduction (USR) and overshoot reduction (OSR) provide fast transient response, low output capacitance, and good dynamic current sharing. The device also provides novel phase interleaving strategy and dynamic phase shedding for efficiency improvement at different loads. 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.
The TPS53689 device is offered in a thermally enhanced 40-pin QFN packaged and is rated to operate from –40°C to 125°C.
