The NEX30606UA from Nexperia is a Step-Down Converter that converts an input voltage of 1.8-5 V to an output voltage of 0.7-3.3 V. It delivers an output current of 600 mA. This converter has a low operating quiescent current of 220 nA. It utilizes a constant on-time (COT) control to maintain low power consumption and provides a fast transient response. This converter offers 16 fixed output voltage options that can be configurable with a VSET pin. It is available as a wafer that measures 3 x 2 mm and is suitable for wearable electronics, smart meters, asset tracking devices, medical sensor patches and monitors, industrial IoT/narrowband (NB)-IoT, and 3 x AA battery-powered applications.
