LD39115J18R Frequently Asked Questions (FAQ)

  • STMicroelectronics recommends a 2-layer or 4-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.

  • Implement a thermal management strategy, such as heat sinks, thermal interfaces, or fans, to keep the junction temperature below 150°C. Also, ensure proper PCB design and layout to minimize thermal resistance.

  • STMicroelectronics recommends using X5R or X7R ceramic capacitors with a minimum capacitance of 10uF for the input and output, and a voltage rating of at least 10V for the input and 6V for the output.

  • Implement overcurrent protection using a fuse or a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse, and consider adding a short-circuit protection circuit to prevent damage from excessive current.

  • Apply the input voltage (VIN) before enabling the enable pin (EN) to ensure proper startup and prevent unwanted behavior.
