Bit 7 | HOLD_DCDC1:
0 = DCDC1 is disabled when HOLD_DCDC1 pin is pulled LOW and PB_IN is released HIGH 1 = DCDC1 stays enabled when HOLD_DCDC1 pin is pulled LOW and PB_IN is released HIGH |
Bit 6 | DCDC_DISCH:
0 = DCDC1 output is not discharged when DCDC1 is disabled 1 = DCDC1 output is discharged when DCDC1 is disabled |
Bit 5..0 | Output voltage setting for DCDC1:
For reference only: A voltage change in the register will not have an effect on the output voltage for TPS65720 and TPS65721 as the voltage is set by an external resistor divider. Contact TI in case a fixed voltage version is needed. |
A voltage change during operation must not exceed 8% of the value set in the register for each I2C write access as this may trigger the internal power good comparator and will trigger the Reset of the device. This limitation is only for a voltage step to higher voltages. There is no limitation for programming lower voltages by I2C. | |
