QM48T50012 DC-DC Converter Data Sheet

36-75 VDC Input; 1.2 VDC @ 50A Output

When using remote sense, the output voltage at the con-

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:

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.

where,

RT−DECR = Required value of trim-down resistor [kΩ]

and ∆ is as defined above.

Output Voltage Adjust /TRIM (Pin 6)

The output voltage can be adjusted up 10% or down 10%

relative to the rated output voltage by the addition of an ex-

ternally connected resistor. For detailed description of the

trim feature and pre-calculated trimming resistor values, see

Application Note 103.

Converters are also available with alternative trim equations,

to provide the customers with the flexibility of second sourc-

ing:

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. C. A trim resis-

tor, R_T-INCR, should be connected between the TRIM (Pin 6)

and SENSE(+) (Pin 7), with a value of:

For these converters, the last character in the part number is

“T”.

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 10% of V_OUT(NOM),

or:

VO−REQ = Desired (trimmed) output voltage [V].

This equation is applicable for any condition of output sens-

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.
