Output Voltage Programming The output voltage of the DCL can be programmed to any voltage between 0.69Vdc and 5.5Vdc by connecting one resistor (shown as Rtrim in Figure 33) between the TRIM and GND pins of the module. Without this external resistor, the output voltage of the module is 0.69 Vdc. To calculate the value of the resistor Rtrim for a particular output voltage Vo, please use the following equation: K Vo Rtrim 69 . 0 9 . 6 Rtrim is the external resistor in kΩ Vo is the desired output voltage. For example, to program the output voltage of the DCL module to 5.0Vdc, Rtrim is calculated as follows: K K Rtrim 601 . 1 69 . 0 0 . 5 9 . 6 Figure 33: Circuit configulation for programming output voltage using an external resister. Table 1 provides Rtrim values required for some common output voltages. By using a ±0.5% tolerance trim resistor with a TC of ±100ppm, a set point tolerance of ±1.5% can be achieved as specified in the electrical specification. Certain restrictions apply on the output voltage set point depending on the input voltage. These are shown in the Output Voltage vs. Input Voltage Set Point Area plot in Fig. 34. The Upper Limit curve shows that for output voltages of 0.9V and lower, the input voltage must be lower than the maximum of 14V. The Lower Limit curve shows that for output voltages of 3.3V and higher, the input voltage needs to be larger than the minimum of 4.5V Figure 34: Output voltage vs input voltage setpoint area plot showing limits were the output can be set for different.input voltage. |
