I.C.
FUNCTION
Voltage Supply Input. SUP powers up the internal linear regulator. Connect a 1 F F
capacitor to ground.
Inductor Switching Node. Connect a Schottky diode between LX and GND.
Internal High-Side Switch-Supply Input. SUPSW provides power to the internal switch.
Connect a 1 F F and 4.7 F F capacitor to ground.
SUP Voltage-Compatible Enable Input. Drive EN low to disable the device. Drive EN
high to enable the device.
Internally Connected. Connect to ground for proper operation.
Exposed Pad. Connect EP to a large-area contiguous copper ground plane for effective
EP
power dissipation. Do not use as the only IC ground connection. EP must be connected
to GND.
