Input voltage for buck converter DCD1 and it also serves as the power supply pin for the whole internal digital/analog
circuits.
Feedback pin for DCD1, connect external voltage divider resistors between DCDC1 output, this pin and ground. For
fixed output versions, connect this pin directly to the DCD1 output.

Output voltage of LDO1.
Output voltage of LDO2.
Input voltage for LDO2.
Power ground for LDO1 and LDO2.
The DCDPG pin is an open-drain output to indicate the state of the DCD1/DCD2 output voltages. When both DCD1
and DCD2 are enabled, the output is released to be pulled high by an external pull-up resistor if both converter
voltages are within the power good range. The pin will be pulled low if either DCD is outside their range. When only
one DCD is enabled, the state of the enabled DCD’s output will define the state of the DCDPG pin. The DCDPG state
can be programmed for a delay of up to 200ms before being released to rise high. The programming range is
1ms~200ms through the I
