Package
Pinout
1. SW (Pin 1): Switch node. Connects to the inductor; this pin is where the switching action occurs.
2. GND (Pin 2): Ground. Provides a reference point for the internal circuitry and power ground.
3. FB (Pin 3): Feedback. Used to set the output voltage by connecting to a resistor divider from the output.
4. EN (Pin 4): Enable. Allows for the device to be turned on or off. A high level on this pin enables the device, while a low level disables it.
5. VIN (Pin 5): Input voltage. Powers the device and should be connected to the input supply voltage.
The LMR54410DBVR is designed for efficient power conversion in a compact form factor, making it suitable for space-constrained applications.
