ROHM FAQ

FAQ's
  • Why do input ripple voltages and spike noise occur?
    • Output ripple currents also flow on the input side. Because of these currents and the input capacitor ESR, ripple voltages occur in the input as well. Spike noise occurs due to current changes accompanying turn-on and turn-off of output switching transistors, and to parasitic inductances in current paths. In order to reduce spike noise, parasitic inductances must be made smaller.
