Pinout
1. SW (Pins 1, 2): The switch node connected to the inductor, and is the drain of the internal high-side power MOSFET.
2. GND (Pin 3): Ground pin.
3. FB (Pin 4): Feedback pin used to set the output voltage.
4. COMP (Pin 5): Compensation node. This pin is used to stabilize the control loop with an external RC network.
5. EN (Pin 6): Enable pin. A high level turns on the regulator, and a low level turns it off.
6. VIN (Pin 7): Power supply input pin.
7. BOOT (Pin 8): Bootstrap pin for the internal high-side MOSFET gate driver.
The MP4688DN-LF-Z is designed for applications requiring efficient voltage regulation from a higher input voltage to a lower output voltage, such as in consumer electronics, telecom, and industrial power systems.
