3 Description
The TLV6208x family devices are small buck
converters with few external components, enabling
cost effective solutions. They are synchronous step-
down converters with an input voltage range of 2.5
and 2.7 (2.5 V for TLV62080, 2.7 V for TLV62084x)
to 6 V. The TLV6208x devices focus on high-
efficiency step-down conversion over a wide output
current range. At medium to heavy loads, the
TLV6208x converters operate in PWM mode and
automatically enter 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 wide range
of external output capacitor values. With the DCS-
Control™ (Direct Control with Seamless transition
into Power save mode) architecture excellent load
transient performance and output voltage regulation
accuracy are achieved. The devices are available in
2-mm × 2-mm WSON package with Thermal Pad.
