■ BD9775FV (1channel synchronous rectification configuration)
● Description
BD9775FV is Switching Controller with synchronous rectification(BD9775FV is 1channel synchronous rectification) and wide
input range. It can contribute to ecological design(lower power consumption) for most of electronic equipments.
● Features (BD9775FV)
1) 2channel Step-Down DC/DC FET driver
2) Synchronous rectification for channel 2
3) Able to synchronize to an external clock signal
4) Over Current Protection (OCP) by monitoring VDS of P channel FET
5) Short Circuit Protection (SCP) by delay time and latch method
6) Under Voltage Lock Out (UVLO)
7) Thermal Shut Down (TSD)
8) Package : SSOP-B28
● Applications (BD9775FV)
Car navigation system, Car Audio, Display, Flat TV
● Absolute maximum ratings (Ta=25 ℃ )(BD9775FV)
