Notes:
3. The -VOUT pin should not be connected to the
“ground” input.
4. The external capacitors shown in the typical
connection diagram below are required to meet
specified operation. Recommended component
values are given in the table at right.
1. The Max input voltage level of the DC/DC con-
verter must be less than the maximum specified
input of the MDCFM-xxU.

2. The maximum power of the DC/DC converter must
be less than the maximum output power of the
MDCFM-xxU.
