PRODUCTION DATA
The voltage output for dual DCP01B devices is half wave rectified; therefore, the discharge time is 1.25 μs. Repeating the above calculations using the 100% load resistance of 50 ? (0.1 A per output), the results are:
τ = 25 μs
tDIS = 1.25 μs
VDIS = 244 mV
VESR = 10 mV
Ripple Voltage = 133 mV
This time, it is the capacitor discharging that contributes to the largest component of ripple. Changing the output filter to 10 μF, and repeating the calculations, the result is:
Ripple voltage = 25 mV
This value is composed of almost equal components.
The previous calculations are offered as a guideline only. Capacitor parameters usually have large tolerances and can be susceptible to environmental conditions.
