PRODUCTION DATA
The output voltage can be set using the VSEL pin. The resistor divider ratio for VSEL programs the VOUT_COMMAND range, VOUT_SCALE_LOOP divider, VOUT_MIN, and VOUT_MAX levels according to Table 6-12. Select the resistor divider code for the range of VOUT desired. For this 1.2-V output example, resistor divider code 4 or a single resistor to AGND.
With the resistor divider code selected for the range of VOUT, select the resistor to AGND code with the VOUT_COMMAND Offset and VOUT_COMMAND step from Table 6-13. To calculate the resistor to AGND code subtract the VOUT_COMMAND offset from the target output voltage and divide by the VOUT_COMMAND step. For this example, a single resistor to AGND was used and the result is code 14. A 68.1-kΩ resistor to AGND at VSEL programs the desired setting.
