Instructions for LT3517EUF

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply ensuring it is within the operating range of 4.5V to 60V.

2. Output Configuration:

   • Set the desired output voltage (VOUT) using external resistors according to the datasheet formula.
   • Ensure the load current does not exceed the maximum continuous output current of 1.2A.

3. Switching Frequency Adjustment:

   • The switching frequency is fixed at 1.1MHz. No external components are required for frequency adjustment.

4. Efficiency Considerations:

   • For optimal efficiency, operate within recommended input and output voltage ranges. Efficiency can reach up to 90% under typical conditions.

5. Thermal Management:

   • Monitor the device temperature to avoid exceeding the thermal shutdown threshold of 160掳C. Proper heat sinking may be necessary depending on application conditions.

6. Quiescent and Shutdown Currents:

   • The quiescent current is typically 70渭A with no load, and the shutdown current is approximately 1渭A at VIN = 12V.

7. Package Handling:

   • Handle the LT3517EUF with care as per standard semiconductor handling practices to avoid damage from electrostatic discharge (ESD).
