3 Description

The TPS62085, TPS62086, and TPS62087 devices

are high-frequency synchronous step-down

converters optimized for small solution size and high

efficiency. With an input voltage range of 2.5 V to

6.0 V, common battery technologies are supported.

The devices focus on high-efficiency step-down

conversion over a wide output current range. 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.

To address the requirements of system power rails,

the internal compensation circuit allows a large

selection of external output capacitor values ranging

from 10 µF to 150 µF. Together with its DCS-Control

architecture, excellent load transient performance and

output voltage regulation accuracy are achieved. The

devices are available in a 2-mm × 2-mm VSON

package.
