SM91501ALO-E Frequently Asked Questions (FAQs)

  • Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • The SM91501ALO-E is rated for operation from -40°C to 125°C. Ensure proper thermal management by providing adequate heat sinking, and avoiding hot spots on the PCB. Also, consider the thermal resistance of the device and the PCB material when designing the system.
  • Bourns recommends using a 10uF to 22uF X7R or X5R ceramic capacitor with a voltage rating of 10V or higher. The capacitor should be placed as close as possible to the VIN pin to ensure proper decoupling.
  • The EN pin should be pulled high during power-up and pulled low during power-down sequences. It's recommended to use a pull-up resistor and a capacitor to filter out noise and ensure a clean enable signal.
  • The maximum allowed output current for the SM91501ALO-E is 1.5A. However, it's recommended to derate the output current based on the ambient temperature and the PCB's thermal design to ensure reliable operation.
