Instructions for MP1482DS MP1482 SOP8

1. Input Voltage (VIN):

   • The input voltage should be within the range of 2.7V to 5.5V.
   • Ensure that the input voltage is stable and does not exceed the maximum rating to avoid damage.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted between 0.6V and 5.2V.
   • Use external resistors to set the desired output voltage according to the formula: ( V_ = V_ left(1 + fracright) ), where ( V_ = 0.6V ).

3. Output Current (IOUT):

   • The typical output current is 2A, with a maximum of 3A.
   • Ensure that the load does not exceed the maximum output current to prevent overheating or damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 25μA at VIN = 5V, VOUT = 3.3V, and IOUT = 0A.
   • This value helps in determining the power consumption when the device is active but not driving any load.

5. Shutdown Current (ISD):

   • The shutdown current is typically 1μA when VIN = 5V and the enable pin (EN) is set to 0V.
   • Use the enable pin to control the operation of the device, setting it to 0V to turn off the device and save power.

6. Efficiency (η):

   • The efficiency is typically 92% at VIN = 5V, VOUT = 3.3V, and IOUT = 1A.
   • High efficiency reduces power loss and heat generation, making the device suitable for applications where power efficiency is critical.

7. Switching Frequency (fSW):

   • The switching frequency is fixed at 1.5MHz.
   • This high-frequency operation allows for the use of smaller external components, reducing the overall size of the design.

8. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 250mV at IOUT = 3A.
   • This parameter indicates the minimum difference between VIN and VOUT required to maintain regulation.

9. Enable Voltage (VEN):

   • The enable pin (EN) must be pulled above 1.2V to activate the device.
   • To disable the device, pull the EN pin below 1.8V.

10. Thermal Shutdown Temperature (TSD):

    • The device will automatically shut down if the temperature exceeds 160°C to prevent damage from overheating.
    • Ensure proper heat dissipation by using a heatsink or placing the device in a well-ventilated area.

Additional Notes:

• Always refer to the datasheet for detailed information and specific application notes.
• Use appropriate bypass capacitors on the input and output to ensure stability and reduce noise.
• For optimal performance, follow the recommended PCB layout guidelines provided in the datasheet.
