SLUSDU8B – APRIL 2020 – REVISED SEPTEMBER 2020  
1.8-V to 5.5-V Input, 0.6-/1-A Synchronous Step-Down Converter with I2C/VSEL  
Interface  
1 Features  
3 Description  
•
•
•
•
2.3-μA operating quiescent current  
Up to 4-MHz switching frequency  
1% output voltage accuracy  
DVS output from 0.4 V to 1.9875 V (12.5-mV  
steps)  
I2C user interface to adjust  
The  
TPS6286x  
devices  
are  
high-frequency  
synchronous step-down converters with I2C- and  
VSEL-Interface. They provide an efficient, flexible,  
and high-power density point-of-load DC/DC 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  
the smallest output voltage ripple. Together, with its  
DCS-control architecture, excellent load transient  
performance and tight output voltage accuracy are  
achieved. With the I2C interface and a dedicated  
VSEL pin, the output voltage is quickly adjusted to  
adapt the power consumption of the load to the ever-  
changing performance needs of the application. The  
TPS6286x family is available with two VSEL pins and  
four factory preset voltages to allow usage without I2C  
interface.
