QM48T/S14120 DC-DC Converter Data Sheet

36-75 VDC Input; 12 VDC @ 14 A Output

equal to the product of the nominal output voltage

and the allowable output current for the given

conditions.

See the previous section for a complete discussion

of this requirement.

To decrease the output voltage (Fig. D), a trim

resistor, R_T-DECR, should be connected between the

TRIM (Pin 6) and SENSE(-) (Pin 5), with a value of:

When using remote sense, the output voltage at the

converter 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 converter’s

actual output power remains at or below the

maximum allowable output power.

RTDECR  Required value of trim-down resistor [kꢀ]

and Δ is defined above.

The output voltage can be adjusted up 10% (V_IN

40 V) 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 connected internally between the TRIM

and SENSE(-) pins.

TRIM/SENSE Function Notes:

1. Trim/Sense Functions have limited capability for Vin < 40 V.

where,

2. 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 overvoltage protection (OVP)

circuit. The designer should ensure that the difference between

the voltages across the converter’s output pins and its sense pins

does not exceed 10% of V_OUT(NOM), or:
