3 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.
