The SY20112L is a high efficiency 1.2MHz synchronous step down DC/DC regulator, which is capable of delivering up to 3A output currents. 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.

The SY20112L integrates the reliable latch-off function when output over voltage, output under voltage or thermal shutdown happens.

The SY20112L is in a space saving, low profile SOT563 package.
