3 Description

The TPS6286x devices are high-frequency

synchronous step-down converters with I2C- and

VSEL-Interface. The devices 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 everchanging

performance needs of the application. The

device family is available with two VSEL pins and

four factory preset voltages to allow usage without I2C

interface.
