TRIM INFORMATION
1. The value of Rtrim-up defined as:
2. The output Voltage 3.3V,12V and 15V value of Rtrim are
defined as below:
R1x Vr
Rtrim - up = (
) - Rt (KΩ )
Vo - Vo , nom
Rtrim - up = (
Where: R trim-up is the external resistor in Kohm.
Vo,nom is the nominal output voltage.
Vo is the desired output voltage.
Rtrim - down = R1x (
R1 ,Rt and Vr are internal to the unit and are defined in Table 1.
For example, to trim-up the output voltage of 5.0V module
(VCD40-D48-S5) by 5% to 5.25V, R trim-up is calculated as follows:
Vo – Vo,nom = 5.25 – 5.0 = 0.25V
R1 = 2.32 Kohm
Rt = 8.2 Kohm , Vr= 2.5
Rtrim - up =
Vr x R1x ( R 2 + R3)
) - Rt (KΩ )
(Vo - Vo , nom ) x R 2
Vr x R1
- 1) - Rt (KΩ )
(Vo , nom - Vo ) x R 2
Where: R trim-up is the external resistor in Kohm.
Vo,nom is the nominal output voltage.
Vo is the desired output voltage.
R1, R2, R3, Rt and Vr are internal to the unit and are defined in Table 2.

In order to trim the voltage up or down one needs to connect the trim resistor either between the trim pin and -Vo for trim-up and between trim
pin and +Vo for trim-down. The output voltage trim range is ±10%. This is shown in Figures 1 and 2:
