Instructions for MP3398EGF-Z:
- Input Voltage (VIN): Ensure the input voltage is within the range of 4.5V to 28V. Exceeding this range can damage the device.
- Output Voltage (VOUT): Set the output voltage between 0.8V and 17.5V using external resistors as per the datasheet guidelines.
- Switching Frequency (fSW): The switching frequency can be adjusted between 600kHz and 900kHz depending on the application requirements.
- Quiescent Current (IQ): At no load and with an input voltage of 12V, the quiescent current should be around 30μA.
- Efficiency (η): For optimal efficiency, operate the device at typical conditions where efficiency reaches up to 92%.
- Load Regulation: Maintain load regulation within 0.5% by ensuring stable operation across varying loads.
- Line Regulation: Keep line regulation within 0.1% by maintaining a stable input voltage range.
- Dropout Voltage (VDROPOUT): Ensure the dropout voltage remains low, ideally around 0.3V, to maintain efficient operation.
- Short-Circuit Protection: The device includes internal protection against short circuits, limiting the current to approximately 2.2A.
For detailed design considerations and specific applications, refer to the full datasheet provided by the manufacturer.
