regulator for hard disk drive systems
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
!Features 1) High accurate Feed Back voltage (±2%). 2) Synchronous rectification. 3) Gate drives for external Nch MOSFET’s. 4) Short circuit protector with latch. 5) Under voltage lockout. 6) Soft start circuit. 7) Drives external
NPN transistor for Vpp. 8) Variable switch of Vpp voltage (1.8V or 2.5V).
