4.5 V to 40 V, 600 mA, synchronous step-down converter
The NEX40400 is a high efficiency step-down converter with low operating quiescent current of typically 60 μA. It provides up to 600 mA output with current mode control for fast loop response.
The wide 4.5 V to 40 V input range is suitable for variety of the power step-down applications in industrial and automotive environments. 0.3 μA ultra-low shutdown supply current allows use in battery-powered applications.
High power conversion efficiency across a wide load range is achieved by folding down the switching frequency at light load condition reducing the switching losses.
Frequency foldback helps to prevent inductor current runaway during start-up and to allow operation in both high conversion ratio and low drop-out cases. Thermal shutdown provides reliable and robust operation.
The NEX40400 comes in a cost-effective 6 leads SOT8061-1 (TSOT23-6) plastic, surface-mounted package with 2.9 mm x 1.6 mm body dimensions.

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
