Output Power
TMP Model, triple-output DC/DC converters incorporate a design tradeoff be-
tween total available output power and input voltage range. The total available
power is a function of both the nominal input voltage and the "width" of the
input voltage range. For a given nominal input (24V or 48V), narrower ranges
(2:1 vs. 4:1) have more available power. For a given "width" of input range
(2:1 or 4:1), higher nominal inputs (48V vs. 24V) have more available power.
Each device, as indicated by its part-number suffix (Q12, Q48, D24, D48),
has a total output power limitation of 25, 30, 35 or 40 Watts, respectively.
Observing these power limitations is the user's responsibility.
As indicated by its Part Number Structure, each TMP device is capable of
sourcing up to 5 Amps of +5V current as well as ±1 Amp of auxiliary (±12V

or ±15V) currents. Users have the flexibility of loading any output up to these
limits; however, you must be extremely careful not to exceed the total output
power rating of any given device. If, for example, a device with a 30W power
rating is sourcing 4A from its +5V output (representing 20W of primary output
power), that device can only supply an additional 10W from its auxiliary outputs
(±333mA from ±15V outputs or ±417mA from ±12V outputs).
As a consequence of this "power-allocation" flexibility, the definition of "full
load," as the condition under which performance specifications are tested
and listed, is ambiguous. The following table lists the primary and auxiliary
output currents that DATEL uses to define each device’s "full load."
