VIN Range from 2.9V to 5.5V
Up to 97% Efficiency
The TLV62065 is a high efficient synchronous step
down DC-DC converter. It provides up to 2.0A output
Power Save Mode / 3MHz Fixed PWM Mode
current.
Output Voltage Accuracy in PWM Mode ±2.0%
With an input voltage range of 2.9V to 5.5V the
Output Capacitor Discharge Function
device is a perfect fit for power conversion from a 5V
Typical 18 A Quiescent Current
or 3.3V system supply rail. The TLV62065 operates
100% Duty Cycle for Lowest Dropout
at 3MHz fixed frequency and enters Power Save
Mode operation at light load currents to maintain high

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
Point Of Load (POL)
reduced to less than 1A and an internal circuit
Notebooks, Pocket PCs
discharges the output capacitor.
Portable Media Players
TLV62065 operates with a 1.0H inductor and 10F
Set Top Box
output capacitor.
The TLV62065 is available in a small 2x2x0.75mm 8-
pin SON package.
