E-L6258EA datasheet by STMicroelectronics

E-L6258EA Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the power supply decoupling capacitors close to the device and use a low-ESR capacitor for the output filter.
• How do I ensure stable output voltage regulation?
  Use a high-quality output capacitor with low ESR and a minimum capacitance of 10uF. Ensure the output capacitor is placed close to the device and connected to a low-impedance ground plane.
• What is the maximum input voltage that can be applied to the device?
  The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
• Can I use the E-L6258EA in a high-temperature environment?
  The device is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability.
• How do I protect the device from overcurrent and short-circuit conditions?
  Use an external current-sensing resistor and a fuse or a PTC (Positive Temperature Coefficient) thermistor to protect the device from overcurrent and short-circuit conditions.
