Pinout
The MP3910GK-Z is a DC-DC step-up (boost) converter IC. It comes in a TSOT-23-6 package, which means it has 6 pins. Here is a brief overview of its pin functions:
1. VIN: Supply voltage input. This pin should be connected to the input voltage source.
2. SW: Switch node. This pin is connected to the inductor and is where the internal switch operates.
3. GND: Ground. This is the ground reference for the IC.
4. FB: Feedback. This pin is used to regulate the output voltage by connecting it to a resistor divider that senses the output voltage.
5. EN: Enable. This pin is used to enable or disable the IC. A high voltage on this pin turns the IC on, while a low voltage turns it off.
6. COMP: Compensation. This pin is used to stabilize the control loop with external capacitors and resistors.
