The ETA1017 is a step-up converter that provides a boosted output voltage from a low voltage source. Because of its proprietary design, it starts up at a very low input voltage down to 850mV. Along with its 10uA ultra-low no load input current, it is an ideal choice for single cell alkaline/NiMH battery operations.(点击即可咨询芯片详细信息)
