DESCRIPTION
Chip enable pin. Forcing this pin above 1.5V enables the part. Forcing this
pin below 0.3V shuts down the device. Do not leave EN floating.
Supply voltage input.
Analog ground.
Feedback pin.
Pulling the MODE pin high allows the device to be forced into fixed
frequency operation.
Switch node connection to inductor. This pin connects to the drains of the
internal main and synchronous power MOSFET switches.
Power ground.
