SN6501-Q1: Configuring for 12 volt output

Part Number: SN6501-Q1

Is there an application note on how to configure a SN6501-Q for a 12 volt output with a 5 volt input?   Data sheets shows max output of 14 volts, but all specified transformers only have turn ratios of about 1:2 max.

  • Hi FJ,

    Thanks for considering the SN6501-Q1 in your design. Figure 47 (pg. 21) of the SN6501-Q1 datasheet shows an alternate method to achieve higher output voltages using a typical N = ~ 1.1 transformer. This design can be used with an N = 1.3 or N = 1.7 turns ratio transformer to create an isolated 12V supply. The choice in turns ratio will rest on whether an LDO is used on the final output voltage stage.

    A full bridge rectifier is needed and can pair with 760390014 or 750313769 Wurth transformers; specs for these and other suited parts are shown on table 3 of the same datasheet. The limitation here is load current - you will want to stick with ~130mA and below.

    Please let me know of any follow up questions you have. Since Thanksgiving is this week my responses will be delayed starting Wednesday.


    Respectfully,
