LM2594M-3.3/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.

  • No, the LM2594M-3.3/NOPB is a buck converter, not a boost converter. It can only step down the input voltage, not step it up.

  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout x Rl) / (f x Cout), where Iout is the output current, Rl is the inductor resistance, f is the switching frequency, and Cout is the output capacitance.

  • The minimum input voltage required is 4V, but it's recommended to keep it above 5V for reliable operation.

  • The LM2594M-3.3/NOPB is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for reliable operation.
