open-in-new Find other Buck converters (integrated switch)

Description

The TLV62085 device is a high-frequency synchronous step-down converter 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 and above. Together with its DCS-Control™ architecture, excellent load transient performance and output voltage regulation accuracy are achieved. The device is available in a 2-mm × 2-mm VSON package.
