SLVSB92A –JANUARY 2012–REVISED MARCH 2012

3-MHz 2-A Step-Down Converter in 2-mm x 2-mm SON Package

Check for Samples: TLV62065-Q1

FEATURES

DESCRIPTION

The TLV62065-Q1 is a highly efficient, synchronous

step-down, dc-dc converter with a 1.2-V fixed output

voltage.. It provides up to 2 A of output current.

•

Qualified for Automotive Applications

AEC-Q100 Test Guidance With the Following

Results:

–

Device Temperature Grade 2: –40°C to

105°C Ambient Operating Temperature

Range

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

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

or 3.3-V system supply rail. The TLV62065-Q1

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. For

low-noise applications, the TLV62065-Q1 can be

forced into fixed-frequency PWM mode by pulling the

MODE pin high.

Device HBM ESD Classification Level H2

Device CDM ESD Classification Level C3B

•

V_INRange from 2.9 V to 5.5 V

Up to 97% Efficiency

Power-Save Mode / - MHz Fixed PWM Mode

Output Voltage Accuracy in PWM Mode ±2.0%

Output Capacitor Discharge Function

Typical 18-µA Quiescent Current

In the shutdown mode, the current consumption is

reduced to less than 1 µA and an internal circuit

discharges the output capacitor.

The TLV62065-Q1 operates with a 1-µH inductor and

10-µF output capacitor.

100% Duty Cycle for Lowest Dropout

For Improved Feature Set See TPS62065

Available in a 2-mm × 2-mm × 0.75-mm SON

The TLV62065-Q1 is available in a small 2-mm × 2-

mm × 0.75-mm 8-pin SON package.
