3-MHz 2A Step Down Converter in 2x2 SON Package

Check for Samples: TPS62065, TPS62067

FEATURES

DESCRIPTION

•

3 MHz Switching Frequency

V_INRange from 3.0V to 6V

The TPS6206x is

synchronous step down DC-DC converters. They

provide up to 2.0A output current.

family of highly efficient

Up to 97% Efficiency

Power Save Mode / 3MHz Fixed PWM Mode

Power Good Output

With an input voltage range of 3.0V to 6V the device

is a perfect fit for power conversion from a 5V or 3.3V

system supply rail. The TPS6206x operates at 3MHz

fixed frequency and enters Power Save Mode

operation at light load currents to maintain high

efficiency over the entire load current range. The

Power Save Mode is optimized for low output voltage

ripple. For low noise applications, TPS62065 can be

forced into fixed frequency PWM mode by pulling the

MODE pin high. TPS62067 provides an open drain

power good output.

Output Voltage Accuracy in PWM Mode ±1.5%

Output Capacitor Discharge Function

Typical 18 µA Quiescent Current

100% Duty Cycle for Lowest Dropout

Voltage Positioning

Clock Dithering

Supports Maximum 1mm Height Solutions

Available in a 2x2x0.75mm SON

In the shutdown mode, the current consumption is

reduced to less than 1µA and an internal circuit

discharges the output capacitor.

APPLICATIONS

•

POL

TPS6206x family is optimized for operation with a tiny

1.0µH inductor and a small 10µF output capacitor to

achieve smallest solution size and high regulation

performance.

Notebooks, Pocket PCs

Portable Media Players

DSP Supply

The TPS6206X is available in a small 2x2x0.75mm

8-pin SON package.
