Part Number: LM53635-Q1

Hi Team,

1. Can TPS53635 passed CISPR25 level 5 without spear spectrum function?

2. What is the side-effect of spear spectrum function? Eff? anything else?

Thank you.

  • Hi Kevin,

    Pls refer to the TIDA-00987   CISPR 25 Class 5 USB Type-C™ Port which use LM53635 without spread spectrum.

    LM53635 use Intelligent pseudo random generator to modulate Fsw within +/-3% range, so it almost has no impact on eff and output ripple.
