Description
1COMP
Error amplifier output. Connects to the compensation network.
2
EN
Chip enable pin. Active HIGH. Connects to a power source through a 10K to100K resistor to enable.
3
BOOT
Connect to 0.1 µF capacitor from VSW to BOOT to power the high side gate driver.
4VSW
Inductor Connection. Connect an output filter inductor to this pin. VSW is high impedance when the IC is
in shutdown mode.
5
GND
GROUND pin.
6VIN
Supply voltage.
7VREG
Internal regulator output. An external 4.7 µF decoupling capacitor is required at this pin.
8
FB
Output voltage feedback input.
