STMicroelectronics provides a recommended PCB layout in the application note AN5096, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, output voltage, and output current. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the input voltage, and a capacitance value between 1uF to 10uF. Refer to the application note AN5096 for more detailed guidance.
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 circuit to ensure the EN pin voltage remains within the specified range.
The TS4962MEIKJT is rated for operation up to 150°C (junction temperature). However, the device's performance and reliability may degrade at high temperatures. It's essential to ensure proper thermal management and consider derating the device's specifications according to the application note AN5096.
STMicroelectronics provides a troubleshooting guide in the application note AN5096, which covers common issues such as output voltage regulation, overcurrent protection, and thermal shutdown. Additionally, using a oscilloscope to monitor the input and output voltages, as well as the EN pin, can help identify the root cause of the issue.
