Datasheet Summary
1.5A, 2.25MHz Synchronous Step-Down DC/DC Regulator
DESCRIPTION
The EUP3291 is synchronous step-down DC-DC converters optimized for battery powered portable applications. The 2.7V to 5.5V input voltage range makes EUP3291 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 EUP3291 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 EUP3291 has internal soft start...
