STMicroelectronics – L6984, L6986 Energy saving synchronous DC-DC converters for industrial
Up to 2 A and up to 38 V input voltage range synchronous step down with extremely low quiescent current
ST’s L6984 and L6986, are perfect solutions for industrial applications. These devices are able to provide up to 2 A of continuous output current and with a wide
input voltage range from 4 V up to 38 V, accordingly to the part number chosen.
High flexibility is given by several adjustable parameters, like output voltage, switching frequency and synchronization capability. Moreover the extreme low
operating quiescent current makes these devices suitable for energy saving and low power consumption stand-by applications.
