BD9734KV

The BD9734KV has 3 features.The first one is controls up to 7 switching regulators:step-up converter,step-down converter,configurable for step-up or step-down coverster,step-up converter for LED.The second one is synchronous rectifying action mode built-in FET transistor.The third one is positive-negative regulator with soft start for CCD supply.

The BD9734KV has some absolute maximum ratings(Ta=25).When parameter is power supply voltage,the symbol is VBAT1,2,VCC,PVCC,the limits is -3.0 to 8.5,the unit is V.When parameter is power supply voltage,the symbol is PVCCH,PVCCL,the limits is -3.0 to 15,the unit is V.When parameter is power dissiption,the symbol is Pd,the limits is 610,the unit is mW.When parameter is power dissiption,the symbol is Pd,the limits is 1200,the unit is mW.When parameter is operating temperature,the symbol is Topr,the limits is -25 to +85,the unit is .When parameter is storage temperature,the symbol is Tstg,the limits is -55 to +125,the unit is .

The BD9734KV described in this specification is designed to be used with ordinary electroic equipment or devices (such as audio-visual equipment,office-automation equipment,communications devices,electrical appliances,and electronic toys.)Should you intend to use BD9734KV with equipment or devices which require an extremely high level of reliability and the malfunction of which would directly endanger human life (such as medical instruments transportation equipment,aerospace machinery,nuclears,fuel controllers and other safety devices),please be sure to consuit with our sales representative in advance.ROHM assumes no responsibilty for the use any circuits described herein,conveys no license under any patent or other right,and makes no representations that the circuits are free from patent infringement.
