UC2846N Frequently Asked Questions (FAQ)

  • The UC2846N can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.

  • The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific design requirements.

  • The soft-start pin is used to slowly ramp up the output voltage during startup to prevent inrush currents. Connect a capacitor from the SS pin to ground, and the IC will slowly charge the capacitor to control the output voltage rise time.

  • The voltage drop across the output diode can be compensated by adding a diode voltage drop (typically 0.7V) to the output voltage setting resistor (R2) calculation. This ensures the output voltage is accurate and regulated.

  • The UC2846N can deliver up to 3A of output current, but this depends on the input voltage, output voltage, and thermal considerations. Be sure to check the thermal derating curves in the datasheet to ensure reliable operation.
