STMicroelectronics recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern under the device to ensure optimal thermal performance. A minimum of 2 oz copper thickness is recommended.
To ensure EMC, STMicroelectronics recommends following the guidelines in the application note AN2679, which provides guidance on PCB layout, component selection, and shielding. Additionally, the device should be placed at least 10 mm away from any metal objects or shields.
STMicroelectronics recommends using a 10 μF to 22 μF X7R or X5R ceramic capacitor with a voltage rating of 25 V or higher. The capacitor should be placed as close as possible to the VIN pin.
STMicroelectronics recommends using an external overvoltage protection (OVP) circuit, such as a voltage supervisor or a dedicated OVP IC, to protect the device from voltage transients and surges. The OVP circuit should be designed to trigger at a voltage level above the maximum recommended input voltage of 18 V.
The recommended operating temperature range for the L9822EPD013TR is -40°C to 125°C. However, the device can operate up to 150°C for short periods of time, but this may affect its reliability and lifespan.
