Instructions for Use:
Input Voltage (VIN):
- Ensure the input voltage is within the range of 2.7V to 5.5V.
- Do not exceed the maximum input voltage to avoid damaging the device.
Output Voltage (VOUT):
- The output voltage can be adjusted between 0.8V and 5.25V.
- Use external resistors to set the desired output voltage according to the datasheet formula.
Output Current (IOUT):
- The device can provide a continuous output current of up to 1.2A, with a peak of 1.5A.
- Ensure the load does not exceed these limits to prevent overheating or damage.
Quiescent Current (IQ):
- The quiescent current is typically 40μA, which is the current consumed by the device when it is active but not driving any load.
Shutdown Current (ISD):
- When the shutdown pin is activated, the device consumes only 1μA of current, effectively turning it off.
Switching Frequency (fSW):
- The switching frequency is fixed at 1.2MHz, which helps in reducing the size of external components like inductors and capacitors.
Efficiency (η):
- The typical efficiency of the device is 90%, which means it is highly efficient in converting input power to output power.
Operating Temperature (TOPR):
- The device can operate within a temperature range of -40°C to 125°C.
- Ensure the ambient temperature and heat dissipation are managed to keep the device within this range.
Storage Temperature (TSTG):
- The device can be stored in temperatures ranging from -65°C to 150°C.
- Store the device in a dry and cool place to maintain its integrity.
Package:
- The MP3391EF-LF-Z is available in an SOIC-8 package.
- Follow standard PCB design guidelines for mounting and soldering the device to ensure reliable performance.
Additional Notes:
- Always refer to the datasheet for detailed specifications and application notes.
- Use appropriate decoupling capacitors near the input and output pins to ensure stable operation.
- Ensure proper PCB layout to minimize noise and improve performance.
