Hi,
Could you let me know what LM5576's operating frequency is specified 50k~ 500kHz even though the integrated oscillator is upto 1MHz? And TINA simulation actually shows me a well-regulation when I set fsw>500kHz. Can I design LM5576 with fsw>500kHz if TINA works well? Otherwise, is there specific reason why the frequency below 500kHz is recommended?
