4A, SYNCHRONOUS STEP DOWN DC-DC CONVERTER DESCRIPTION FEATURES The A7114 is a high-efficiency, DC-DC step-down  Duty Cycle 0~100% switching regulators, capable of delivering up to 1.
4A  1.
4A Output Current of output current.
The device operates from an input  High Efficiency Up To 96% voltage range of 2.
5V to 6.
0V and provides an output  2.
5V to 6.
0V Input Voltage Range voltage from 0.
6V to VIN, making the A7114 ideal for low voltage power conversions.
Running at a fixed frequency of 1.
5MHz allows the use of small external    Fixed 1.
5MHz Frequency Logic Control Shutdown IQ<1μA Thermal Shutdown components, such as ceramic input and output caps,  Output Adjustable from 0.
6V to Input Voltage as well as small inductors, while still providing low  Available in SOT-25 Package output ripples.
This low noise output along with its APPLICATION excellent efficiency achieved by the internal synchronous rectifier, making A7114 an ideal green  Digital Framer replacement for large power consuming linear  PDA and Pocket PC regulators.
Internal soft-start control circuitry reduces  Cellular Phone and Smart Phone inrush current.
Short-circuit and thermal-overload  Wireless Devices protection improves design reliability.
