Connect inductor/diode here. The output voltage can go up to 29V but should not 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. Calculate the Output Voltage according to the formula: VOUT = 1.25V * (1+R1/R2) 4 SHDN Shutdown Pin. Connect to 1.5V or higher to enable device (ON), 0.4V or lower to disable device (OFF) 5 VIN Input Supply Pin. Must be locally bypassed Functional Block Diagram
