Transformer for SN6051 Q1
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,Manuel Chavez
