MPQ4558DN-LF-Z Frequently Asked Questions (FAQ)
-
The maximum input voltage is 26V, but it's recommended to keep it below 24V for reliable operation.
-
To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage within the recommended range of 0.8V to 15V.
-
The maximum output current is 5A, but it's recommended to keep it below 4A for reliable operation and to prevent overheating.
-
The power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Make sure to keep the junction temperature below 125°C to prevent overheating.
-
The EN (enable) pin is used to turn the regulator on or off. Connect it to Vin to enable the regulator, or to GND to disable it. You can also use it to implement power sequencing or to turn off the regulator during shutdown.
