Pinout
1. SW (Switch Output): Connects to the inductor. This pin carries the switching current of the regulator.
2. GND (Ground): Ground reference for the device. All control circuits are referenced to this pin.
3. FB (Feedback): Connects to the output of the power supply to set the output voltage via an external resistor divider.
4. EN (Enable): A high level on this pin enables the device; a low level disables it. Can be used for power sequencing.
5. VIN (Input Voltage): Supplies power to the device. This is the input voltage to be regulated.
6. BOOT (Bootstrap Capacitor): Provides a bootstrap capacitor connection for the high-side FET driver.
7. RT (Switching Frequency Setting Resistor): Connects to a resistor to set the switching frequency.
8. NC (No Connection): Typically not connected internally, often used for trace routing purposes.
This concise summary outlines the basic functionality of each pin in the device.
