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 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.

•

1% output voltage accuracy

2.4-MHz switching frequency

Selection by external resistor

– Start-up output voltage
