The maximum input voltage that can be applied to the LM2574M-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 with an ESR of less than 1 ohm. Additionally, the output voltage can be further stabilized by adding a 10nF capacitor between the output and ground.
The maximum output current that the LM2574M-5.0 can provide is 3A. Exceeding this current can cause the device to overheat and potentially fail.
To protect the LM2574M-5.0 from overheating, it is recommended to provide adequate heat sinking, such as a heat sink with a thermal resistance of less than 10°C/W. Additionally, the device should be operated within the recommended temperature range of -40°C to 125°C.
Yes, the LM2574M-5.0 can be used in high-temperature environments, but the device's power rating must be derated accordingly. The device's power rating decreases by 6.25% for every 1°C above 25°C.
