1
LX
PWM output connection to inductor. LX pin needs to be connected externally. Thermal connection
for output stage.
2
BST
Bootstrap voltage input. High side driver supply. Connected to 0.1μF capacitor between BST and
LX.
3
GND
Ground.
4
FB
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.
5
COMP
External loop compensation. Output of internal error amplifier. Connect a series RC network to
GND for control loop compensation.
6
EN
Enable pin. The enable pin is active HIGH. Connect EN pin to V
pin floating.
