Product Details
BD9845FV is an IC containing a circuit of switching regulator controller by pulse width modulation system. This circuit can be used for step-down DC/DC converter operation. In addition, the package is designed compact, and is optimum for compact power supply for many kinds of equipment.
High voltage resistance input (Vcc=35V)
FET driver circuit is contained (step-down circuit 1 output).
Error amplifier reference voltage (1.0V±1%) and REG output circuit (2.5V) are contained.
Over current detection circuit is contained.
Soft start and pause period can be adjusted.
Three modes of standby, master, and slave can be switched. (ices=0μA typ in standby mode.)
ON / OFF control is enabled independently for each channel. (DT terminal)
Applications:
Refrigerator
