SN6505B: 5Vin to +/-12Vout

Part Number: SN6505B
Other Parts Discussed in Thread: TIDA-01159

Hi Sir 

May I know SN6505B have reference design include transformer  p/n for 5Vin to +/-12Vout?

Thanks 

  • Hi Kai,

    Do you know what is output current requirement on both +12V and -12V? Do you know if +12V and -12V need to be isolated from each other?

    If the two outputs are not required to be isolated from each other and output current requirement is <80mA then you can use the transformer used with SN6505B in the TI design TIDA-01159. To get bipolar output, please use a full bridge rectifier as shown below (also shown in Figure 48 of SN6505 datasheet).

    If you need higher output current then you can use the transformers listed at the link below along with a full bridge rectifier.
