Pin Description
Bootstrap. This pin acts as the power supply for internal Power Transistor driver.
Connect a 10nF capacitor between this pin and SW pin.
Ground and heat sink. Connect this pin to a large copper PCB area.
Feedback voltage input. The voltage of this pin is regulated to 0.81V. The shielding in the
PCB layout is option and connect resistor divider as close as possible.
Chip enable input. The Enable voltage range is higher than 1.2V and disable voltage is
lower than 0.4V.
Power supply input. The input bypass capacitor should be as close as GND pin.
Switching node. The free-wheeling diode is connected between this pin and GND.
