Pinout
1. SW (Pin 1): Switch Node. This pin connects to the inductor and is the switching node where the inductor is connected.
2. GND (Pin 2): Ground. This is the ground return for the IC and must be connected to the system ground.
3. FB (Pin 3): Feedback. This pin is used to set the output voltage via a resistor divider network.
4. EN (Pin 4): Enable. This pin is used to enable or disable the device. A high level on this pin enables the device.
5. VIN (Pin 5): Input Voltage. This is the supply voltage input to the converter.
6. BOOT (Pin 6): Bootstrap. This pin provides a boost voltage for the high-side gate driver.
The LM2734XMK is designed for applications requiring efficient power conversion, with the ability to deliver up to 1A output current.
