TPS62130A Differences to TPS62130: SLVA644 WebIn general, a peak-to-peak ripple current is chosen to be between 10% and 60% of the DC output current. Why does ripple current matter? Ideally, any DC-DC converter (LDO, Buck, Boost, etc.) produces a stable, low-noise output voltage from an imperfect (noisy, variable) input voltage. Ripple current induces a corresponding ripple in the ...
