Output Trim Equations  
1. Output Voltage Adjustement by applying external voltage. The Vtrim must add at Trim and Sense(-), the  
output voltage measure must between at Sense(+) and Sense(-).

2. Output Voltage Adjustement by applying external resistor  
The Trim down resistor should be connected between the Trim pin and Sense(+) pin. The Trim up resistor  
should be connected between the Trim pin and the Sense(-). Only one of the resistors should be used for any  
given application. The output voltage measure must between at Sense(+) and Sense(-).
