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 QFN package.
