SY8843
Overview
The SY8843 and SY8843L are high efficiency 1.5MHz synchronous step down DC/DC regulators capable of delivering up to 3A output current. The SY8843 and SY8843L can operate over a wide input voltage range from 2.7V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
- 2.7~5.5V Input Voltage Range
