Package : TO263-5L
RoHS : YES
SI-8000FDL series features an oscillation frequency of 300kHz, allowing downsizing of the choke coil. Also, the TO-263-5 package realizes a compact, and highly efficient power supply.
The SI-8001FDL is a chopper type switching regulator IC which is provided with various functions required for the buck switching regulator and built-in functions for overcurrent and thermal shutdown . By using six external components, a highly efficient switching regulator can be composed.
Compact size and large output current of 3.5A
Built-in on/off function (active Low)
