STMicroelectronics recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure good thermal dissipation.
To ensure reliable operation in high-temperature environments, it's essential to follow proper thermal management practices, such as providing adequate airflow, using a heat sink, and ensuring good thermal interface material (TIM) between the device and heat sink.
STMicroelectronics recommends using X7R or X5R ceramic capacitors with a voltage rating of 10V or higher for input and output capacitors. The recommended capacitance values are 10uF for input and 22uF for output.
To protect the device from overvoltage and undervoltage conditions, it's recommended to use a voltage supervisor or a power-on reset (POR) circuit to monitor the input voltage and reset the device if it falls outside the recommended operating range.
The recommended startup sequence for the TS1220-600B is to first apply the input voltage, followed by the enable signal. This ensures that the device is properly biased and configured before enabling the output.
