Instructions for XLSEMI XL7035E1:

1. Input Connection:

   • Connect the input voltage (VIN) within the operating range of 3.0V to 42.0V to the designated input pin.

2. Output Configuration:

   • Set the desired output voltage using an external resistor divider connected to the feedback pin (FB). The adjustable range is from 1.25V to 40.0V.

3. Switching Frequency:

   • The default switching frequency is set at 700kHz. This can be adjusted if needed by connecting an external resistor to the RT pin.

4. Efficiency Optimization:

   • For optimal efficiency, ensure the load current and input voltage are within recommended ranges. Maximum efficiency is typically achieved around 94% under standard conditions.

5. Output Ripple Control:

   • To minimize output ripple, use appropriate output capacitors. The typical ripple voltage is 20mV peak-to-peak under standard load conditions.

6. Thermal Considerations:

   • Ensure adequate heat dissipation for higher output currents. Refer to the thermal design guidelines in the datasheet.

7. Protection Features:

   • The device includes overcurrent and overtemperature protection. Ensure these features are not frequently triggered by maintaining proper operating conditions.

8. Layout Recommendations:

   • Follow good PCB layout practices to minimize noise and parasitic effects. Keep high-current paths short and wide, and place decoupling capacitors close to the IC.
