3 Description
The TPS62868 and TPS62869 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. Through the I 2C
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.
