Pinout
1. SW (Switch Output): Connects to the inductor and provides the switching action to regulate the output voltage.
2. GND (Ground): Ground reference for the device.
3. FB (Feedback): Used to set the output voltage via a resistor divider connected to the output.
4. VIN (Input Voltage): Supplies the input voltage to the converter.
5. EN (Enable): Enables or disables the device. A high level turns the converter on, while a low level turns it off.
6. BST (Bootstrap): Provides voltage to the internal high-side MOSFET driver.
This configuration allows the LM2736YMKX to efficiently convert a higher input voltage to a lower output voltage, making it suitable for applications requiring efficient power conversion.
