Q24S30015 DC-DC Converter Data Sheet
18-36 VDC Input; 1.5 VDC @ 30A Output
load. Therefore, the designer must, if necessary, decrease
the maximum current (originally obtained from the derating
curves) by the same percentage to ensure the converter’s
actual output power remains at or below the maximum al-
lowable 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
converter‘s maximum allowable output power. See previous
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 0.15 V, or:
0.15
