TECHNICAL NOTE  
Large Current External FET Controller Type Switching Regulator  
Dual-output  
High-frequency step-down  
Switching Regulator (Controller type)  
BD9842FV  
Overview  
BD9842FV is an IC containing two circuits of switching regulator controller by pulse width modulation system.  
Both of two circuits 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.  
Feature  
1) High voltage resistance input (Vcc=35V)  
2) FET driver circuit is contained (step-down circuit 2 output).  
3) Error amplifier reference voltage (1.0V±1%) and REG output circuit (2.5V) are contained.  
4) Overcurrent detection circuit is contained.  
5) Soft start and pause period can be adjusted.  
6) Three modes of standby, master, and slave can be switched. (iccs = 0 uA typ in standby mode.)  
7) ON/OFF control is enabled independently for each channel. (DT terminal)  
Application  
LCD, PDP, PC, AV, Printer, DVD, Projector TV, Fax, Copy machine, Measuring instrument, etc.
