(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
