Texas Instruments provides a recommended PCB layout in the TIR2000PAG evaluation module documentation, which includes guidelines for component placement, trace routing, and thermal management. Following this layout can help ensure optimal performance and minimize electromagnetic interference (EMI).
The output capacitor selection depends on the specific requirements of your application, such as output voltage ripple, transient response, and EMI filtering. TI recommends using a low-ESR capacitor with a value between 10uF to 22uF, and a voltage rating of at least 2x the output voltage. Additionally, consider the capacitor's physical size, temperature rating, and reliability.
While the datasheet specifies an operating temperature range of -40°C to 125°C, the maximum ambient temperature for reliable operation depends on the specific application and thermal management. As a general guideline, TI recommends keeping the ambient temperature below 85°C to ensure optimal performance and reliability.
The TIR2000PAG has a built-in OCP and SCP feature, which can be enabled by connecting the OCP pin to a resistor and capacitor network. The OCP threshold can be set by adjusting the resistor value, and the SCP response time can be adjusted by changing the capacitor value. Refer to the datasheet and application notes for detailed implementation guidelines.
TI recommends using a high-quality, low-ESR input capacitor with a value between 10uF to 22uF, and a voltage rating of at least 2x the input voltage. A ceramic or film capacitor with an X7R or X5R dielectric is suitable for most applications. The input capacitor helps to filter input voltage noise and reduce electromagnetic interference (EMI).
