SY8105I regulator equivalent, synchronous step down regulator.
* Low RDS(ON) for Internal Switches (Top/Bottom): 41mΩ/27mΩ
* 4.5-18V Input Voltage Range
* 5A Output Current Capability
* 500kHz Switching Frequency Mini.
and high efficiency at light loads. In addition, it operates at pseudo-constant frequency of 500kHz to minimize the size.
The SY8105I is a high efficiency 500kHz synchronous step-down DC/DC regulator, which is capable of delivering up to 5A load current. It can operate over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch wit.
