Feature Descriptions
Output Voltage Programming (continued)
For example, to program the output voltage of the
Austin MiniLynx
calculated is follows:
Figure 32. Circuit configuration to program
output voltage using an external resistor.
Table 1 provides Rtrim values required for some
common output voltages.
Using 1% tolerance trim resistor, set point
tolerance of ±2% is achieved as specified in the
electrical specification. The POL Programming
Tool, available at
the Design Tools section, helps determine the
required external trim resistor needed for a specific
output voltage.
