Q24T30025 DC-DC Converter Data Sheet
18-36 VDC Input; 2.5 VDC @ 30A Output
When using remote sense, the output voltage at the con-
verter can be increased by as much as 10% above the
nominal rating in order to maintain the required voltage
across the load. Therefore, the designer must, if necessary,
decrease the maximum current (originally obtained from the
derating curves) by the same percentage to ensure the con-
verter’s actual output power remains at or below the maxi-
mum allowable output power.
Output Voltage Adjust /TRIM (Pin 6)
The converter’s output voltage can be adjusted up 10% or
down 20% relative to the rated output voltage by the addition
of an externally connected resistor.
The TRIM pin should be left open if trimming is not being
used. To minimize noise pickup, a 0.1 F capacitor is con-
nected internally between the TRIM and SENSE(-) pins.
To increase the output voltage, refer to Fig. 4. A trim resistor,
RT-INCR, should be connected between the TRIM (Pin 6) and
SENSE(+) (Pin 7), with a value of:

When trimming up, care must be taken not to exceed the

section for a complete discussion of this requirement.
To decrease the output voltage (Fig. 5), a trim resistor,
RT-DECR, should be connected between the TRIM (Pin 6) and

Trimming/sensing beyond 110% of the rated output voltage
is not an acceptable design practice, as this condition could
cause unwanted triggering of the output over-voltage protec-
tion (OVP) circuit. The designer should ensure that the dif-
ference between the voltages across the converter’s output
pins and its sense pins does not exceed 0.25 V, or:
0.25
