Q24T30015 DC-DC Converter Data Sheet

18-36 VDC Input; 1.5 VDC @ 30A Output

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

ter 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 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.

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

and Δ is as defined above.

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.

Note: The above equations for calculation of trim resistor

values match those typically used in conventional industry-

standard quarter bricks.

To increase the output voltage, refer to Fig. 4. A trim resistor,

_T-INCR, should be connected between the TRIM (Pin 6) and

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

(V^O-REQ V^O-NOM)

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:

VOREQ  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,

R_T-DECR, should be connected between the TRIM (Pin 6) and

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