Instructions for Use:

1. Input Voltage (V_IN):

   • Ensure the input voltage is within the range of 4.5V to 60V.
   • Do not exceed the maximum input voltage to avoid damaging the device.

2. Output Voltage (V_OUT):

   • The output voltage can be adjusted between 0.8V and 58.5V.
   • Use an external resistor network to set the desired output voltage.

3. Output Current (I_OUT):

   • The device can provide a continuous output current up to 3A.
   • For optimal performance, keep the output current around 2A.

4. Switching Frequency (f_SW):

   • The typical switching frequency is 1.0 MHz.
   • This frequency helps in achieving high efficiency and small external component sizes.

5. Quiescent Current (I_Q):

   • The quiescent current is typically 70 渭A at no load and V_IN = 12V.
   • This low quiescent current ensures efficient operation even at light loads.

6. Shutdown Current (I_SD):

   • When the enable pin (EN) is set to 0V, the shutdown current is typically 1 渭A.
   • Use this feature to minimize power consumption when the device is not in use.

7. Efficiency (畏):

   • The efficiency is typically 95% at V_IN = 12V, V_OUT = 5V, and I_OUT = 1A.
   • Optimize the design for these conditions to achieve the highest efficiency.

8. Thermal Shutdown (T_SD):

   • The device will shut down if the junction temperature exceeds 160掳C.
   • Ensure proper heat dissipation to prevent thermal shutdown.

9. Storage Temperature (T_STG):

   • Store the device in an environment with temperatures ranging from -40掳C to 150掳C.
   • Avoid storing in extreme temperatures to maintain device integrity.

10. Operating Junction Temperature (T_J):

    • The operating junction temperature should be kept between -40掳C and 150掳C.
    • Use appropriate cooling methods to keep the junction temperature within this range during operation.
