A7120
DC-DC CONVERTER BUCK (STEP-DOWN)
2A 1.4MHz 5.5V SYNCHRONOUS BUCK CONVERTER
DESCRIPTION
The A7120 is a high efficiency synchronous buck
regulator. The device operates from an input voltage
range of 3.6V to 5.5V and provides an output voltage
from 0.8 to 5V while delivering up to 2A of output
current.
The internal synchronous switches increase
efficiency and eliminate the need for an external
Schottky diode. The switching frequency is set by an
external resistor or can be synchronized to an
external clock. While switching frequency is set to
1.4MHz, A7120 can allow the use of small external
components, such as ceramic input and output caps,
as well as small inductors, while still providing low
output ripples.
100% duty cycle provides low dropout operation
extending battery life in portable systems.
The A7120 is available in SOP8 package.
