3 Description

The TPS6208x devices are a family of high frequency

synchronous step down converters. With an input

voltage range of 2.3 V to 6 V, common battery

technologies are supported. Alternatively, the device

can be used for low voltage system power rails.

The TPS6208x focuses 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 currents to maintain high

efficiency over the entire load current range. To

maintain high efficiency at very low load or no load

currents, a Snooze Mode with an ultra-low quiescent

current is implemented. This function, enabled by the

MODE pin, increases the run-time of battery driven

applications and keeps the standby current at its

lowest level to meet green energy standards targeting

a low stand-by current.

To address the requirements of system power rails,

the

internal

loop

compensation

allows

a

large

selection of external output capacitor values in

excess

of

100

µF.

With

its

DCS-Control™

architecture, excellent load transient performance and

output voltage regulation accuracy is achieved. The

device is available in 2-mm × 2-mm WSON package

with Thermal PAD.
