Pinout
1. IN (Pin 1): Input voltage pin where the supply voltage is applied.
2. OUT (Pin 8): Output voltage pin that delivers power to the load.
3. GND (Pin 4): Ground pin for the device.
4. ILIM (Pin 2): Current limit set pin. Connect a resistor between ILIM and GND to set the desired current limit.
5. EN/UVLO (Pin 3): Enable/Undervoltage lockout pin. A high input enables the device, and it can also be used to set the undervoltage lockout threshold.
6. SS (Pin 5): Soft-start pin. Connect a capacitor to GND to control the ramp-up time during startup.
7. OVLO (Pin 6): Overvoltage lockout pin. Use a resistor divider from the input voltage for setting the overvoltage threshold.
8. FLT (Pin 7): Fault pin, which is an open-drain output that indicates a fault condition when pulled low.
This device ensures circuit protection with adjustable current limiting, overvoltage, and short-circuit protection features.
