6.4 VOUT1 Register (Address = 4h) [reset = 3Ch]
Table 8 shows the VOUT1 register.
Return to Summary Table .
This register sets the device output voltage when the VSEL pin is low. This register is volatile, so it loses
its contents if the voltage on the VIN pin becomes less than the UVLO threshold or a low logic level is
applied to the EN pin.

7 RESERVED R 0b Reserved
6-0 VOUT1 R/W 0111100b These bits set the output voltage of the converter when the VSEL pin
is low.
When the RANGE bit = 0, the output voltage in volts is
1.8 + (VOUT1 × 0.025).
When the RANGE bit = 1, the output voltage in volts is
2.025 + (VOUT1 × 0.025).
