The maximum input voltage that can be applied to the LM2585S-12 is 15V, but it's recommended to keep it below 14V to ensure reliable operation and to prevent damage to the internal circuitry.
The LM2585S-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. Consult the datasheet for more information on thermal derating.
To ensure the stability of the LM2585S-12 output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Additionally, keep the input and output capacitors close to the device and use a good quality PCB layout to minimize noise and oscillations.
Yes, you can use multiple LM2585S-12 devices in parallel to increase the output current, but make sure to use a common input capacitor and a common output capacitor, and to wire the outputs in parallel. Also, ensure that the devices are thermally coupled to prevent thermal runaway.
The minimum input voltage required for the LM2585S-12 to operate is 7.2V, but it's recommended to keep the input voltage above 8V to ensure reliable operation and to prevent dropout.
