CB |
I |
SW FET gate bias voltage. Connect CBOOT capacitor between CB and SW. |
2 |
GND |

Ground connection |
3 |
FB |
I |
Feedback pin: Set feedback voltage divider ratio with VOUT = VFB (1 + (R1 / R2)). Resistors must be from 100 Ω to 10 kΩ to avoid input bias errors. |
4 |
SHDN |
I |
Logic level shutdown input. Pull to GND to disable the device and pull high to enable the device. If this function is not used tie to VIN . DO NOT ALLOW TO FLOAT. |
5 |
VIN |
I |
Power input voltage pin: 4.5-V to 42-V normal operating range. |
6 |
SW |
O |
Power FET output: Connect to inductor, diode, and CBOOT capacitor. |
