TPS53667RTAT

直流/直流控制器, 降压稳压器, 4.5 V至17 V, 1输出, 1MHZ, WQFN-40

The TPS53667 is a high-current, multi-phase, step-down controller. The device offers built-in non volatile memory NVM and PMBus interface. It is compatible with the NexFET power stages CSD9549x. The TPS53667 provides 8-bit BOOT voltage selection covering output voltage from 0.5 V to 2.5 V, with steps as small as 5 mV, which is ideal for high current application with accurate output voltage setting. Advanced control features such as D-CAP+ architecture with undershoot reduction USR and overshoot reduction OSR provide fast transient response, lowest output capacitance, and high efficiency. The TPS53667 also provides novel phase interleaving strategy and dynamic phase shedding for efficiency improvement at light loads. In addition, the TPS53667 supports the PMBus communication interface with systems for telemetry of voltage, current, power, temperature, and fault conditions. Some of the configurations can be programmed by pinstrap or PMBus and stored in non-volatile memory to minimize the external component count.

The TPS53667 is offered in a space saving, thermally enhanced 40-pin QFN package and is rated to operate from –40°C to 125°C.
