EUP3418 - Eutech Microelectronics

EUP3418 1A Synchronous Step-Down Converter

The EUP3418 is a constant frequency, current mode, PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency. The 2.7V to 5.5V input voltage range makes the EUP3418 ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery or 3-cell NiMH/ NiCd batteries. The output voltage .
