Manufacturer: Texas Instruments

Overview: www.ti.com TPS62868, TPS62869 SLVSFS3A – SEPTEMBER 2020 – TREPVSIS6E2D86D8E,CTEMPBSE6R22806290 SLVSFS3A – SEPTEMBER 2020 – REVISED DECEMBER 2020 TPS62868x 2.4-V to 5.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS62868 and TPS62869 devices are highfrequency 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
