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)  
RTDECR = Required value of trim-down resistor [k]  
and is as defined above.  
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.  
Note: The above equations for calculation of trim resistor  
values match those typically used in conventional industry-  
standard quarter bricks.  
The TRIM pin should be left open if trimming is not being  
used. To minimize noise pickup, a 0.1 µF capacitor is con-  
nected internally between the TRIM and SENSE(-) pins.  
To increase the output voltage, refer to Fig. 4. A trim resistor,

Fig. 5: Configuration for decreasing output voltage.  
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:  
(VO-REQ VO-NOM)

X 100 [%]

VOREQ = Desired (trimmed) output voltage [V].  
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.

This equation is applicable for any condition of output sens-  
ing and/or output trim.  
To decrease the output voltage (Fig. 5), a trim resistor,  
RT-DECR, should be connected between the TRIM (Pin 6) and  
SENSE(-) (Pin 5), with a value of:
