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_DAC = 1.5V_OUT) when V_IN > V_OUT. Bypass mode is
enabled when the DAC voltage exceeds 1.2V or V_IN ≤ V_OUT. V_OUT = V_DAC x 3.
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.
Output of the LDO2.
Drain of internal bypass switch, also serves as feedback for the internal regulator.
Power ground.
Switch: Internal power MOSFET output switches of DC/DC converter.
Supply Voltage: Requires bypass capacitor to ground.
Enables LDO1 Regulator.
Enables the DC/DC Converter.
Supply voltage for DC/DC converter control circuitry and reference voltage circuit. Must be connected
to PIN 5.
No Connect.
