FUNCTION
Status LED Cathode Outputs (Open-Drain Low-Side)
Fault LED Cathode Outputs (Open-Drain Low-Side)
LED Anode Connections (Open-Drain High-Side). Connect a resistor in series to set the diode
current.
Charge-Pump Flying Capacitor
Charge-Pump Flying Capacitor. Connect a 200nF/50V capacitor to CFN.
Charge-Pump Output. Connect a 10μF/5V capacitor between VPMP and V_DD. VPMP is not
intended for use as a power supply for other devices.
Ground. Connect all GND pins together.
DC-DC Converter Switching Output. Connect LX to the switching-side of the inductor.
