LM2574MX-5.0 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2574MX-5.0 is 40V. Exceeding this voltage can cause damage to the device.
-
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage can be stabilized by adding a 10nF capacitor between the output and ground.
-
The minimum input voltage required for the LM2574MX-5.0 to operate is 7V. However, the device can operate down to 4V with reduced performance.
-
The LM2574MX-5.0 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures.
-
The output voltage ripple of the LM2574MX-5.0 can be calculated using the formula: ΔVout = (Iout x Rload) / (f x Cout), where ΔVout is the output voltage ripple, Iout is the output current, Rload is the load resistance, f is the switching frequency, and Cout is the output capacitance.
