Feedback input for switching regulator. Connect to an external resistor divider from output to program the
output voltage.
Feedback input for the LDO. Connect to an external resistor divider from V
5 V power input for internal analog circuits and gate drives. Connect to external 5 V supply or configure the
LDO for 5 V and connect to V
Analog ground.
Output voltage input to the SiC417. Additionally, may be used to bypass LDO to supply V
Input supply voltage.
LDO output.
Bootstrap pin. A capacitor is connected between BST to LX to develop the floating voltage for the high-side
gate drive.
High-side gate drive - do not connect this pin.
Low-side gate drive - do not connect this pin.
Switching (Phase) node.
Power ground.
Open-drain power good indicator. High impedance indicates power is good. An external pull-up resistor is
required.
Current limit sense point - to program the current limit connect a resistor from I
Tri-state pin. Enable input for switching regulator. Connect EN to A
Float pin for forced continuous and pull high for power-save mode.
On-time set input. Set the on-time by a series resistor to the input supply voltage.
Enable input for the LDO. Connect ENL to A
