Feature Descriptions
Trim Up – Increase Output Voltage
By connecting an external resistor between the TRIM pin
and Vout- pin (Radj-up), the output voltage set point
increases (see figure 48). The following equation
determines the external resistor value to obtain an
output voltage change from Vo, nom to the desired Vo,
adj:
Note: Values for G, H, L and K are defined for each
module version in the following table 1.
Figure 48. Circuit Configuration to Increase Output
Voltage.
Table 1. Trim Constants SW series
The combination of the output voltage adjustment and
the output voltage initial tolerance must not exceed the
allowable trim range of 90% to 110% of the nominal
output voltage as measured between the Vout+ and
Vout- pins.
The SW/SC power modules have a fixed current-limit set
point. Therefore, as the output voltage is adjusted down,
the available output power is reduced.
