NXP provides a recommended PCB layout in the application note AN11542, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, current, and frequency. NXP recommends using a low-ESR capacitor with a value between 4.7uF to 10uF, and a voltage rating of at least 1.5 times the input voltage. Refer to the application note AN11542 for more details.
The maximum allowed voltage on the EN (enable) pin is 6V. Exceeding this voltage may damage the device. It's recommended to use a voltage divider or a buffer to ensure the EN pin voltage remains within the specified range.
Proper biasing is critical for optimal performance. Ensure the input voltage is within the specified range (7V to 30V), and the EN pin is properly biased (high or low) according to the application requirements. Refer to the datasheet and application notes for more information.
The recommended operating temperature range for the SSL21083AT/1,118 is -40°C to +125°C. However, the device can operate up to +150°C with derating. Refer to the datasheet for more information on temperature derating.
