TLV62065

SLVSAC4B – NOVEMBER 2010 – REVISED DECEMBER 2015

TLV62065 3-MHz 2-A Step-Down Converter in 2 × 2 WSON Package

1 Features

3 Description

The

TLV62065

device

is

a

high

efficiency

1

•

VIN Range from 2.9 V to 5.5 V

synchronous

step-down

DC–DC

converter.

It

•

Up to 97% Efficiency

provides up to 2-A output current.

•

Power-Save Mode / 3-MHz Fixed PWM Mode

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

•

Output Voltage Accuracy in PWM Mode ±2.0%

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

•

Output Capacitor Discharge Function

or 3.3-V system supply rail. The TLV62065 operates

at 3-MHz fixed frequency and enters power-save

•

Typical 18-µA Quiescent Current

mode operation at light load currents to maintain high

•

100% Duty Cycle for Lowest Dropout

efficiency over the entire load current range. For low

•

Available in a 2 mm × 2 mm × 0.75 mm WSON

noise applications, TLV62065 can be forced into fixed

frequency PWM mode by pulling the MODE pin high.

2 Applications

In the shutdown mode, the current consumption is

•

Point-of-Load (POL)

reduced to less than 1 µA and an internal circuit

discharges the output capacitor.

•

Notebooks, Pocket PCs

•

Portable Media Players

TLV62065 operates with a 1-µH inductor and 10-µF

output capacitor.

•

Set-Top Boxes

The TLV62065 is available in a small 2 mm × 2 mm ×

0.75 mm 8-pin WSON package.
