Feature Descriptions (continued)

Output Voltage Set-Point Adjustment (Trim)

(continued)

With an external resistor connected between the TRIM

and SENSE(+) pins (Radj-up), the output voltage set

point (VO, adj) increases (see Figure 15).

The following equation determines the required exter-

nal-resistor value to obtain a percentage output voltage

change of

The test results for this conguration are displayed in

Figure 16.

The voltage between the VO(+) and VO(–) terminals

must not exceed the minimum value of the output over-

voltage protection as indicated in the Feature Speci-

cations table. This limit includes any increase in voltage

due to remote-sense compensation and output voltage

set-point adjustment (trim). See Figure 12.

Although the output voltage can be increased by both

the remote sense and by the trim, the maximum

increase for the output voltage is not the sum of both.

The maximum increase is the larger of either the

remote sense or the trim. Consult the factory if you

need to increase the output voltage more than the

above limitation.

The amount of power delivered by the module is

dened as the voltage at the output terminals multiplied

by the output current. When using remote sense and

trim, the output voltage of the module can be

increased, which at the same output current would

increase the power output of the module. Care should

be taken to ensure that the maximum output power of

the module remains at or below the maximum rated

power.
