TPS62065, TPS62067

SLVS833C – MARCH 2010 – REVISED JULY 2015

TPS6206x 3-MHz, 2-A, Step-Down Converter in 2-mm × 2-mm SON Package

1 Features

3 Description

The

TPS6206x

is

a

family

of

highly

efficient

1

•

3-MHz Switching Frequency

synchronous step down DC/DC converters. They

•

provide up to 2-A output current.

•

Up to 97% Efficiency

With an input voltage range of 2.9 V to 6 V, the

•

Power Save Mode / 3-MHz Fixed PWM Mode

device is a perfect fit for power conversion from a 5-V

•

Power Good Output

or 3.3-V system supply rail. The TPS6206x operates

at 3-MHz fixed frequency and enters power save

efficiency over the entire load current range. The

•

Typical 18 µA Quiescent Current

power save mode is optimized for low output voltage

ripple. For low noise applications, TPS62065 can be

•

100% Duty Cycle for Lowest Dropout

forced into fixed frequency PWM mode by pulling the

power good output.

•

Supports Maximum 1-mm Height Solutions

In the shutdown mode, the current consumption is

•

Available in a 2 mm x 2 mm x 0.75 mm WSON

reduced to less than 1 µA and an internal circuit

discharges the output capacitor.

2 Applications

TPS6206x family is optimized for operation with a tiny

•

Point of Load (POL)

1 µH inductor and a small 10-µF output capacitor to

achieve smallest solution size and high regulation

•

Notebooks, Pocket PCs

performance.

•

Portable Media Players

The TPS6206x operates over a free air temperature

•
