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.
