ABB FemtoDLynxII Non-Isolated DC-DC Power Modules

ABB FemtoDLynxII™ Non-Isolated DC-DC Power Modules are non-isolated DC-DC power modules available in 3A or 6A output current configurations. These buck converters offer a wide 4.5VDC to 14.4VDC input voltage range while using an external resistor for a programmable output voltage of 0.6VDC to 5.5VDC. The modules have an open-frame design measuring 6.76mm x 9mm x 7.2mm and use Tunable Loop™ to optimize the dynamic output voltage response. These easy-to-use, point-of-load (PoL) modules do not require external components to supply an external bias voltage. ABB FemtoDLynxII Non-Isolated DC-DC Power Modules are ideal for industrial, networking, intermediate bus voltage, and server/storage applications as well as distributed power architectures and telecommunications equipment.
