I am looking at the DC DC converter ADP1111. My application is to convert +24V
to -24V.
Can you please advice me, can this part fulfill my requirement.


ADP1111 is very old product, and ADP2300/1 is a new one. But looking at the
below customer requirement for 24V to -24V, both of them can NOT do it, because
of voltage rating limitation: [Vin]+[Vout] < Maximum Operation Voltage.

However, this can be done by ADP1621, attached please find its application
notes for positive to negative DC/DC application. And need the parameters
changes according to the SPEC.
