SLVSAC4A –NOVEMBER 2010–REVISED JULY 2012

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

Check for Samples: TLV62065

FEATURES

DESCRIPTION

The TLV62065 is a high efficient synchronous step

down DC-DC converter. It provides up to 2.0A output

current.

•

V_INRange from 2.9V to 5.5V

Up to 97% Efficiency

Power Save Mode / 3MHz Fixed PWM Mode

Output Voltage Accuracy in PWM Mode ±2.0%

Output Capacitor Discharge Function

Typical 18 µA Quiescent Current

100% Duty Cycle for Lowest Dropout

For Improved Feature Set See TPS62065

Available in a 2x2x0.75mm SON

With an input voltage range of 2.9V to 5.5V the

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

or 3.3V system supply rail. The TLV62065 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. For low

noise applications, TLV62065 can be forced into fixed

frequency PWM mode by pulling the MODE pin high.

APPLICATIONS

In the shutdown mode, the current consumption is

reduced to less than 1µA and an internal circuit

discharges the output capacitor.

•

Point Of Load (POL)

Notebooks, Pocket PCs

Portable Media Players

Set Top Box

TLV62065 operates with a 1.0µH inductor and 10µF

output capacitor.

The TLV62065 is available in a small 2x2x0.75mm 8-

pin SON package.
