EUP3402 Dual 1A, 2.25MHz Synchronous Step-Down DC/DC Regulator DESCRIPTION The EUP3402 is synchronous dual step-down DC-DC converters optimized for battery powered portable applications. It provides two independent output voltage rails powered by 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. With an input voltage range of 2.7V to 5.5V, the EUP3402 is ideal to power portable applications like smart phones, PDAs and other portable equipment. The EUP3402 operates at 2.25MHz fixed switching frequency allowing the use of small inductors and capacitors to achieve a small solution size. Each output supports up to 1A load current, typical.
