Hi TI Power-Experts,
I need to generate two voltages to supply internally my device:
- the fist output U1 must give about 7V @ 5W. It supplies linear regulators (3V3, 5V, etc) supplying internal digital circuits
- the second output U2 must give 14V 5% @ 10W. It supplies the power stage. The power stage is floating therefore the U2 must be an isolated output
The input voltage range is 4V5 - 36V (automotive). The controller must be AEC-Q100 certified for automotive applications.
I have chosen two topologies - either conventional FlyBack or dual output SEPIC as illustrated below:
Could you suggest any TI controller IC for these both topologies. Thank you!
