7.3.6 VERSA-COMP Pin Configurations
The versa-comp feature of the LMZ34202 allows a simple method to adjust the internal compensation network to provide the optimized phase and gain margin based on the output voltage. This easy-to-use feature requires no external components and is implemented by the simple configuration of two adjacent pins on the module.
The versa-comp feature must be configured in one of two ways; VERSA-COMP pin left OPEN or VERSA-COMP pin tied to VADJ. The output voltage determines the appropriate Versa-Comp pin configuration. Table 8 lists the Versa-Comp configuration. Figure 19 shows the two possible Versa-Comp pin configurations.
Figure 19. Versa-Comp Configurations Table 8. VERSA-COMP Pin Configurations
| VOUT RANGE (V) | VERSA-COMP PIN CONFIGURATION | |
|---|---|---|
| MIN | MAX | |
| 2.5 | < 3.0 | OPEN |
| 3.0 | 7.5 | Connect to VADJ |
