3-MHz 1.6A Step Down Converter in 2x2 SON Package

Check for Samples: TPS62060

FEATURES

DESCRIPTION

•

3 MHz Switching Frequency

V_INRange from 2.7V to 6V

The TPS62060 is a highly efficient synchronous

step-down DC-DC converter and provides up to 1.6A

output current.

1.6A Output Current

Up to 97% Efficiency

With an input voltage range of 2.7V to 6V the device

is a perfect fit for power conversion from a single

Li-Ion battery as well from 5V or 3.3V system supply

rails. The TPS62060 operates at 3-MHz 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, the device can be forced into fixed

frequency PWM mode by pulling the MODE pin high.

Power Save Mode / 3 MHz Fixed-PWM Mode

Output Voltage Accuracy in PWM Mode ±1.5%

Output 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

TPS62060 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.
