Pin Function
DAC Control Input (Analog Voltage Input). Provides control of output voltage of DC/DC converter.
The output voltage is 3x’s the DAC voltage (Ex. 0.5V
enabled when the DAC voltage exceeds 1.2V or V
Filter capacitor for LDO1 and LDO2 internal voltage reference, connect capacitor to ground.
Signal ground of chip.
Enables the LDO2 regulator.
LDO1 and LDO2 Supply Voltage. Must be connected to PIN 15.
Output of the LDO1.
