DESCRIPTION
FEATURES
The A7110 is a high-efficiency, DC-to-DC step-down
switching regulators, capable of delivering up to 1.0A
of output current. The device operates from an input
voltage range of 2.5V to 6.5V and provides an output
voltage from 0.6V to VIN, making the A7110 ideal for
low voltage power conversions.
High Efficiency: Up to 96%
Capable of Delivering 1.0A
1.5MHz Switching Frequency
No External Schottky Diode Needed
Low dropout 100% Duty operation
Internal Compensation and Soft-Start
Current Mode control
Running at a fixed frequency of 1.5MHz allows the
use of small external components, such as ceramic
input and output caps, as well as small inductors,
while still providing low output ripples. This low noise
output along with its excellent efficiency achieved by
the internal synchronous rectifier, making A7110 an
ideal green replacement for large power consuming
linear regulators. Internal soft-start control circuitry
reduces inrush current.
