Table 1 provides Rtrim values required for some common output voltages, By using a 0.5% tolerance trim resistor, set point tolerance of ±1.5% can be achieved as specified in the electrical specification. Table 1 0.6V Open 1V 3K 1.2V 2K 1.5V 1.333K 1.8V 1K 2.5V 0.632K 3.3V 0.444K 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 Figure 32. The Upper Limit curve shows that for output voltages of 3.3V and lower, the input voltage must be lower than the maximum of 5.5V. The Lower Limit curve shows that for output voltages of 1.8V and higher, the input voltage needs to be larger than the minimum of 2.4V. Figure 32: Output Voltage vs. Input Voltage Set Point Area plot showing limits where the output voltage can be set for different input voltages. Voltage Margining Output voltage margining can be implemented in the DCM modules by connecting a resistor, R margin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to the output pin for margining-down. Figure 33 shows the circuit configuration for output voltage margining. If unused, leave the trim pin unconnected. A calculation tool is available from the evaluation procedure which computes the values of Rmargin-up and Rmargin-down for a specific output voltage and margin percentage.

This is accomplished via an additional sequencing pin. When not using the sequencing feature, either tie the SEQ pin to VIN or leave it unconnected. When an analog voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches the set-point voltage. The final value of the SEQ voltage must be set higher than the set-point voltage of the module. The output voltage follows the voltage on the SEQ pin on a one-to-one basis. By connecting multiple modules together, multiple modules can track their output voltages to the voltage applied on the SEQ pin. |
