SI-8008HD
Package : TO263-5L
RoHS : YES
SI-8000HD series attains an oscillation frequency of 150kHz, and has an integrated miniaturized choke coil, allowing it to serve as a high efficiency power supply in a compact TO-263 package.
SI-8000HD series regulators provides various features and protection functions (overcurrent and thermal protection) which are necessary for switching regulators.
Only 7 external components are required, and provides high efficiency switching regulation without any need for adjustment.
The device supplies 5.5A output current in a TO-263-5 package.
