NEX30606UA

1.8 V to 5.0 V, 600 mA, 220 nA ultra-low quiescent current, step-down converter

The NEX30606 is a high-efficiency step-down converter with ultra-low operating quiescent current of typically 220 nA.

The device uses COT control (Constant On Time) to achieve low power consumption mode and fast transient, operates with a switching frequency of 1.5 MHz. At light load conditions, it seamlessly enters Power Save Mode to reduce switching cycles and maintain high efficiency.

Output voltage can be configured by VSET pin. For 1.8 V output, connects the VSET pin to GND. For other output voltages, connects resistor to VSET pin following values in Table 1. Sixteen internally set voltages can be selected.

The NEX30606 provides an output current up to 600 mA. With input voltage up to 5.0 V, the devices supports multiple sources such as 2S to 3S Alkaline, 1S Li-MnO2, 1S Li-ion/Li-SOCL2.

The NEX30606 device series comes in a tiny 6-pin WLCSP package with 0.35-mm pitch.

Sample

As a Nexperia customer you can order samples via our sales organization.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.

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.
