EML3470-18V 3A, COT, Synchronous Step-Down DC/DC Converter DataSheet
General Description
EML3470 is a high efficiency step down DC/DC converter. It features very fast transient response, and excellent line and load regulation via constant on time (COT) control architecture. The device can accept input voltage from 4.5V to 18V 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.
