3 Description
The TPS62864 and TPS62866 devices are high-
frequency synchronous step-down converters with I2C
interface which provide an efficient, adaptive, and
high power-density solution. At medium to heavy
loads, the converter operates in PWM mode and
automatically enters Power Save Mode operation at
light load to maintain high efficiency over the entire
load current range. The device can also be forced in
PWM mode operation for smallest output voltage
ripple. Together with its DCS-control architecture,
excellent load transient performance and tight output
voltage accuracy are achieved. Via the I2C interface
and a dedicated VID pin, the output voltage is quickly
adjusted to adapt the power consumption of the load
to the ever-changing performance needs of the
application.
