BD9722FV
BD9722FV is a system
regulator to convert into two systems of power supply from 5V.
One is a synchronous rectification DC/DC controller.
It enables to determine 1.
0~3.
3V output with external resistor and to provide power supply to a high current system.
Another is a series power supply of an external
NPN Tr drive type.
It can be set up either 1.
8V or 2.
5V in a CTL terminal.
!Applications HDD, PC
