EML3470 is a high efficiency step down DC/DC converter. The EML3470 adopts constant on time (COT) control architecture with excellent load and line transient response. The device can accept input voltage from 4.5V to 17V and deliver up to 3A output current. Furthermore, the built-in synchronous switch improves efficiency and eliminates external Schottky diode. The EML3470 uses pulse skip modulation (PSM) for improving light load efficiency, the adjustable version of this device is available in TSOT-23-6 package.
