Regulators BD9722FV System 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).
