Datasheet Summary
EUP3406 1.5MHz, 600mA Synchronous Step-Down Converter
DESCRIPTION
The EUP3406 is a constant frequency, current mode, PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency. The 2.5V to 5.5V input voltage range makes the EUP3406 ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery or 3-cell NiMH/ NiCd batteries. The output voltage can be regulated as low as 0.6V. The EUP3406 supports up to 600mA load current and can also run at 100% duty cycle for low dropout applications, extending battery .. life in portable systems. Switching frequency is internally set at 1.5MHz, allowing the...
