Recommended Voltage Derating Guidelines

Ripple Current/Ripple Voltage

T= Environmental Temperature

Using the P max of the device, the maximum allowable rms

ripple current or voltage may be determined.

I(max) = √P max/R

E(max) = √P max*R

I = rms ripple current (amperes)

E = rms ripple voltage (volts)

Pmax = maximum power dissipation(watts)

R = ESR at specified frequency (ohms)
