PWM output connection to inductor. LX pin needs to be connected externally. Thermal connection
for output stage.
Bootstrap voltage input. High side driver supply. Connected to 0.1µF capacitor between BST and
LX.
Ground.
Feedback input. It is regulated to 0.8V. The FB pin is used to determine the PWM output voltage
via a resistor divider between the output and GND.
External loop compensation. Output of internal error amplifier. Connect a series RC network to
GND for control loop compensation.
Enable pin. The enable pin is active HIGH. Connect EN pin to V
pin floating.
Supply voltage input. Range from 4.5V to 27V. When V
device starts up. All V
Compensation pin of internal linear regulator. Place put a 1µF capacitor between this pin and
ground.
