The TPS62864/6 devices are high-frequency synchronous step-down converters withI2C interface which provide an efficient, adaptive, and highpower-density solution. At medium to heavy loads, the converter operates in PWM mode andautomatically enters Power Save Mode operation at light load to maintain high efficiency over theentire load current range. The device can also be forced in PWM mode operation for smallest outputvoltage ripple. Together with its DCS-control architecture, excellent load transient performanceand tight output voltage accuracy are achieved. Via the I2C interfaceand a dedicated VID pin, the output voltage is quickly adjusted to adapt the load’s powerconsumption to the ever-changing performance needs of the application.
