The device is ideal for use in consumer electronics, industrial products, and distributed power systems where efficient voltage regulation is required.
Pinout
The MP2338GTL-Z comes in a 6-pin TSOT23-6 package. Here is a brief overview of its pin functions:
1. SW (Pin 1): The switch output. Connect this pin to the inductor.
2. GND (Pin 2): Ground. Connect this pin to the system ground.
3. FB (Pin 3): Feedback. Connect this pin to the output voltage divider to set the desired output voltage.
4. EN (Pin 4): Enable. Use this pin to enable or disable the device.
5. IN (Pin 5): Input supply. Connect this pin to the input voltage source.
6. BST (Pin 6): Bootstrap. Connect a capacitor between this pin and the SW pin to drive the gate of the high-side MOSFET.
This pin configuration allows the MP2338GTL-Z to efficiently convert a higher input voltage to a lower output voltage with minimal external components.
