WLCSP6 NEX30606 1.8 V to 5.0 V, 600 mA, 220 nA ultra-low quiescent current, step-down converter Rev. 1 — 20 November 2024 Product data sheet 1. General description 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 5. Sixteen internally set voltages can be selected.
