Output Voltage Set point adjustment.
The following relationship establish the calculation of external resistors for the NEF series:
Trim-Up
For trim_Up an external resistor is connected between the TRIM and Ground Pin.
Where,
Trim_Down
For trim down an external resistor is to be connected between TRIM and Vout pins of the module.
The value of Rtrim_Down is calculated from the following relationship.
The values of R1 , Rt , Vo,num , Vo are as defined above.
Examples:
Vout = 1.5V Trim_Up required 8% to 1.62V
Vo – Vo,nom = 1.62 – 1.5 = 0.12V
Vout = 1.5V Trim_Down required 8% to 1.38V
Vo,nom - Vo = 1.5 – 1.38 = 0.12V
