Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common mode choke or a ferrite bead to filter out high-frequency noise.
To ensure proper biasing, it's essential to follow the recommended biasing circuit in the datasheet. This includes using a voltage divider to set the input bias voltage to around 1.4V, and ensuring the output stage is properly terminated with a 50Ω load.
The TIL3022 is rated for operation from -40°C to 85°C. However, it's essential to note that the device's performance may degrade at higher temperatures, and it's recommended to derate the device's power dissipation accordingly.
While the TIL3022 can be used in switching power supply applications, it's not recommended due to its relatively low power handling capability. Texas Instruments recommends using a more suitable device, such as the TIL3130, for switching power supply applications.
To troubleshoot common issues, start by verifying the PCB layout and ensuring that the input and output traces are properly routed. Check for any signs of oscillation or instability, such as excessive heat or noise. If issues persist, consult the datasheet and application notes for guidance on troubleshooting and debugging.
