LM2574HVN-12 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2574HVN-12 is 40V, but it's recommended to keep it below 37V to ensure reliable operation.
-
To ensure the output voltage is stable and accurate, make sure to use a stable input voltage, choose the correct output capacitor value, and keep the feedback resistors within the recommended range.
-
The minimum input voltage required for the LM2574HVN-12 to operate is around 7V, but it's recommended to keep it above 8V for reliable startup and operation.
-
The LM2574HVN-12 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
-
The output voltage ripple of the LM2574HVN-12 can be calculated using the formula: ΔVout = (Iout * Rcoil) / (2 * fsw * Cout), where Iout is the output current, Rcoil is the inductor resistance, fsw is the switching frequency, and Cout is the output capacitor value.
