BD9722FV
BD9722FV is System regulator manufactured by ROHM.
Regulators
System regulator for hard disk drive systems
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
!Features
