The SY20213B is a high efficiency 3MHz synchronous step down DC/DC regulator IC capable of delivering up to 0.6A output current. It can operate in PFM or CCM mode during light load programed by MODE pin. It can operate over a wide input voltage range from 1.85V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
