Pin	Name	Functions	Notes
BOOT	Bootstrap capacitor connection for high-side MOSFET driver	GPIO	Connect a high-quality 0.1-μF capacitor from BOOT to SW.
VIN	Input voltage pin	POWER	Connect to power supply and bypass capacitors CIN. Path from VIN pin to high-frequency bypass CIN and GND must be as short as possible.
EN	Enable pin with internal pullup current source	GPIO	Pull below 1.2V to disable; float or connect to VIN to enable. Adjust the input undervoltage lockout with two resistors.
RT/SYNC	Resistor timing or external clock input	GPIO	An internal amplifier holds this pin at a fixed voltage when using an external resistor to ground to set the switching frequency. If pulled above the PLL upper threshold, it becomes a synchronization input.
FB	Feedback input pin	GPIO	Connect to the feedback divider to set VOUT. Do not short this pin to ground during operation.
SS or PGOOD	Soft-start version SS pin or Power Good version PGOOD open drain output	GPIO	For soft-start, connect to a capacitor to set soft-start time. For Power Good, use a 10-kΩ to 100-kΩ pullup resistor to logic rail.
GND	System ground pin	GND
SW	Switching output of the regulator	POWER	Internally connected to high-side power MOSFET. Connect to power inductor.
