DESIGN CONSIDERATIONS

1) Recommended circuit

All the VRA_YMD-6WR2 & VRB_YMD-6WR2 Series have been tested according to the following recommended test circuit before leaving the

factory (see Figure 5).

If you want to further decrease the input/output ripple, you can increase a capacitance-values properly or choose capacitors with low ESR, but

the total capacitance of the filter capacitor must not exceed the Max. Capacitive Load.
