Typical application

All the DC/DC converters of this series are tested according to the re-

commended circuit (see Fig. 1) before delivery.

If it is required to further reduce input and output ripple, properly incre-

ase the input & output of additional capacitors Cin and Cout or select

capacitors of low equivalent impedance provided that the capacitance

is no larger than the max. capacitive load of the product.

The product does not support output in parallel with power per liter.
