High-Side Gate Drive Boost Input. This pin acts as the power supply of high-side gate
driving blocks. Connect a 10nF or greater capacitor between SW and BST pin.
Power supply input. Bypass VIN to GND with a suitably large capacitor to eliminate
noise on the input to the IC.
Switching node. The free-wheeling diode is connected between SW and GND.
Ground. Connect the exposed pad on backside to GND.
Feedback voltage input. The regulated FB voltage is 0.2V typically.
Compensation node. COMP is used to compensate the regulation control loop.
Chip enable input. Also this pin functions UVLO input.
Soft start control node. This pin controls the soft start period.
