SY20208A is a high efficiency, 1.5µA ultra low quiescent current, synchronous step down DC/DC regulator special designed for one-cell Li-Ion or Li-polymer battery powered applications. It can operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low R_DS(ON) to minimize the conduction loss.
