ROHM Semiconductor's SBD70522GUL-E2 is a buck converter featuring 180 nA quiescent current and supports output current up to 500 mA. The constant ON-time (COT) control with ultra-low power (ULP) mode provides superior transient response and extends battery life by providing excellent light load efficiency below 10 μA load range. The output voltage can be selected from nine pre-set voltages by VSEL pins. When the input voltage gets close to the output voltage, the IC enters 100% ON mode where the switching operation stops.
