Texas Instruments TPS536C7B1 Step-Down Multiphase PWM Controller

Texas Instruments TPS536C7B1 Step-Down Multiphase PWM Controller comes with dual channels, built-in non-volatile memory (NVM), and PMBus interface and is fully compatible with TI NexFET™ smart power stages. The advanced control features, such as the D-CAP+ architecture, provide a fast transient response, low output capacitance, and good current sharing. The device also provides a novel phase interleaving strategy and flexible firing order. Adjustable control of output voltage slew rate and adaptive voltage positioning is also supported. The device supports the PMBus communication interface for reporting telemetry of voltage, current, power, temperature, and fault conditions to the system host. 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 Texas Instruments TPS536C7B1 is offered in a thermally enhanced 48-pin QFN packaged and is rated to operate from –40°C to 125°C.
