Part Number
SiC417DB
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
