(2) Output Voltage Set-Point Adjustment by using an external voltage source

For IPM12C series

Output voltage of IPM12C is programmable while applying a voltage between the TRIM and GND pins. The following equation can be used to determine the value of Vtrim needed for a desired output voltage Vo:

Vtrim = 0.7439 – 0.0488Vo

Vtrim is the external voltage in V

Vo is the desired output voltage

For example, to program the output voltage of a IPM module to 3.3 Vdc, Vtrim is calculated as follows:

Vtrim = 0.7439 – 0.0488 x 3.3 = 0.5829V

For IPM04C series

Output voltage of IPM04C is programmable while applying a voltage between the TRIM and GND pins. The following equation can be used to determine the value of Vtrim needed for a desired output voltage Vo:

Vtrim = 0.7168 – 0.0187Vo

Vtrim is the external voltage in V

Vo is the desired output voltage

For example, to program the output voltage of a IPM module to 3.3 Vdc, Vtrim is calculated as follows:

Vtrim = 0.7168 – 0.0187 x 3.3 = 0.655V
