Dear TI support,

Can you please let me know the rad-hard pwm controller part number(s) for following applications :

1. Interleaved flyback converter.

2. Two-switch flyback converter.

3. Active clamp flyback converter.

4. Synchronous flyback converter implementing current mode control (prefarably).

    Hey Bhavana,

    The UC1843B-SP is our suggestion for any singled ended applications (one output)

    The UC1825B-SP is our suggestion for applications that need two outputs, but with the outputs 180 degrees out of phase (like a half bridge).

    Unfortunately we do not have a space grade device that has two outputs where the outputs are inversions of each other.

    Our suggestion for that would be to use the UC1843B-SP and make the output discretely.

    Thanks,

    Daniel
