Pinout
The MP1469GJ-Z is a monolithic step-down switch mode converter with integrated MOSFET. It is designed to achieve up to 1.2A continuous output current from a 4.5V to 23V input voltage range, with excellent load and line regulation. The MP1469GJ-Z typically comes in a 6-pin SOT23 package.
Here is a brief overview of the pin functions:
1. VIN: Supply voltage input. The MP1469GJ-Z operates from a 4.5V to 23V input voltage. It requires input capacitors close to this pin to minimize voltage spikes and noise.
2. SW: Switch output. This is the output pin that connects to the inductor for converting the input voltage to a lower output voltage.
3. GND: Ground. It is the ground reference for the IC and must be connected properly in any design.
4. FB: Feedback. This pin is used to set the output voltage via an external resistive divider connected to the output.
5. EN: Enable. A high level on this pin allows the device to operate. A low level will put the device into the shutdown mode.
6. COMP: Compensation. This pin is used for compensation of the control loop, usually through an external RC network.
These components help in achieving efficient power regulation from higher input voltages.
