Power Supply Connection:
- Connect the input voltage (VIN) to the power supply ensuring it is within the operating range of 4.5V to 60V.
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.
Switching Frequency Adjustment:
- The switching frequency is fixed at 1.1MHz. No external components are required for frequency adjustment.
Efficiency Considerations:
- For optimal efficiency, operate within recommended input and output voltage ranges. Efficiency can reach up to 90% under typical conditions.
Thermal Management:
- Monitor the device temperature to avoid exceeding the thermal shutdown threshold of 160°C. Proper heat sinking may be necessary depending on application conditions.
Quiescent and Shutdown Currents:
- The quiescent current is typically 70μA with no load, and the shutdown current is approximately 1μA at VIN = 12V.
Package Handling:
- Handle the LT3517EUF with care as per standard semiconductor handling practices to avoid damage from electrostatic discharge (ESD).
