TIDA-01426: How to modify this design to generate 12V AC out?

Part Number: TIDA-01426

Hi ,

We are thinking of copy this design to generate 12V AC out. 

May i have your suggestion how to modify this design to generate 12V AC out?

  • Hi,

    Assuming 12VAC as RMS Output the peak will voltage will be 16.968V.

    The first change will be turns ratio of transformer (T1) to achieve 50V BUS Voltage

    The second update will be re compute Q point of MOSFET (Q3) and gain as Per section High Gain Amplifier to calculate passive values.
