AS1115-BSST - ams OSRAM

AS1115-BSST Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a large copper area for heat dissipation is recommended. The thermal pad should be connected to a large copper area on the PCB to ensure good heat dissipation.
• How do I ensure the AS1115-BSST is properly soldered?
  Use a reflow soldering process with a peak temperature of 260°C. Ensure the soldering iron is set to a temperature of 350°C to 370°C. Apply a small amount of solder paste to the thermal pad and reflow according to the recommended soldering profile.
• What is the recommended input capacitor value and type for the AS1115-BSST?
  A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor. The capacitor should be placed as close as possible to the VIN pin to minimize noise and ensure stable operation.
• How do I handle the AS1115-BSST's thermal shutdown feature?
  The AS1115-BSST has a built-in thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. To handle this, ensure good heat dissipation, use a heat sink if necessary, and implement a thermal monitoring system to detect and respond to thermal shutdown events.
• What is the recommended output capacitor value and type for the AS1115-BSST?
  A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the output capacitor. The capacitor should be placed as close as possible to the VOUT pin to minimize noise and ensure stable operation.
