EUP3290
1A, 2.
25MHz Synchronous Step-Down DC/DC
Regulator
DESCRIPTION
The EUP3290 is synchronous step-down DC-DC converters optimized for battery powered portable applications.
The 2.
7V to 5.
5V input voltage range makes EUP3290 ideal for powering portable equipment that runs from 1-cell Li-Ion or 3-cell NiMH/NiCD batteries.
The device is also suitable to operate from a standard 3.
3V or 5V voltage rail.
The EUP3290 operates at 2.
25MHz fixed switching frequency allowing the use of small inductors and capacitors to achieve a small solution size.
The internal synchronous switch increases efficiency and eliminates the need for an external
schottky diode.
The EUP3290 has internal soft start and av...
