9 / 15 page DS_IPM12C0A0R04_08242006 9 FEATURES DESCRIPTIONS (CON.) For example: to program the output voltage of the IPM module to 3.3Vdc, Rtrim is calculated as follows: 3.752 Rtrim = 3.3 –0.9 - 0.261 (KΩ) Rtrim = 1.302 KΩ IPM can also be programmed by applying a voltage between the TRIM and GND pins (Figure 32). 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 Vtrim = 0.5829V Figure 30: Trim up Circuit configuration for programming output voltage using an external resistor Figure 32: Circuit configuration for programming output voltage using external voltage source Rtrim Load Vout Trim GND Figure 31: Trim down Circuit configuration for programming output voltage using an external resistor |
