Function

Switch Pin. Connect inductor/diode here. The output voltage can range up to 29V but not

extend this limit. If the voltage on this pin is higher than the overvoltage protection thre-

shold (OVP), the device comes back to shutdown mode. To restart the chip, one must then

send a low to high sequence on shutdown pin or switch off the VIN supply.

Ground Pin.

Voltage Feedback. Reference voltage is 95mV.

Shutdown Pin. Connect to 1.5V or higher to enable device;

Connect to 0.4V or less to disable device.
