Silergy SY8893E
The SY8893E 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 RDS (ON) to minimize the conduction loss. The SY8893E is in a space saving, low profile SOT563 package.| Part No. | SY8893E |
