DESCRIPTION
The TLV62080 device is a synchronous step down
converter with an input voltage range of 2.5V to 5.5V.
The TLV62080 focuses on high efficient 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 currents 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 10µF up to 100uF effective capacitance. With its
DCS-Control^TM architecture excellent load transient
performance and output voltage regulation accuracy
is achieved. The device is available in 2mm x 2mm
SON package with Thermal PAD.
