8.2.4 Output Voltage Set-point Programming

(1) Output Voltage Set-Point Adjustment by external resistor

Output Voltage Set-point Programming can be carried out by using the external program resistor connect between TRIM pin to ground to set output voltage set-point from 0.75Vdc to 5Vdc, the location can refer to the Evaluation Board Schematic (please refer to the data sheet for more the detailed specification). These test functions are divided into two types,

Rset of DNM04S and DNL04S series can be calculated by using the following equation:

Rset

21070

 

 

=

 

 

− 5110

Ω

 

 

 

Vo − 0.7525

 

For example, to program the output voltage of the DNL04 module to 1.8Vdc, below is the calculation of Rtrim:

Rset =

 

 

− 5110

= 15004

Ω

 

 

1.8 − 0.7525

 

 

The table 1 provides the Rset value required for some standard output and the location on the Evaluation board is R33.
