SY20011B
Description
The SY20011B is a 400nA ultra low quiescent current, 1.0MHz synchronous step down DC/DC regulator, which is capable of delivering up to 500mA output current. It can operate over a wide input voltage range from 2.0V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
