Pin Description
Pin Number Pin Name
Function
Switch Pin. Connect inductor/diode here. The output voltage can go up to 29V but should not
1
SW
exceed this limit. If the voltage on this pin is higher than the overvoltage protection (OVP)
threshold, the device can go into shutdown mode. It can be restarted by a low to high pulse on
the SHDN pin, or by a power on reset on the VIN supply
2
GND Ground Pin. Connect directly to local ground plane
3
FB
Feedback Pin. Internally compares to 1.25V. Connect R1 and R2 resistor divider here. Calcu-
late the Output Voltage according to the formula: VOUT=1.25V * (1+R1/R2)
Shutdown Pin. Connect to 1.5V or higher to enable device (ON), 0.4V or lower to disable
