Texas Instruments provides a recommended PCB layout in the TPS2383PM datasheet, which includes guidelines for component placement, routing, and thermal management. Following this layout can help ensure optimal performance and minimize electromagnetic interference (EMI).
The input capacitor should be selected based on the input voltage, current, and ripple requirements. A general rule of thumb is to choose a capacitor with a capacitance value of at least 10uF and a voltage rating of at least 1.5 times the input voltage. Additionally, the capacitor's ESR (Equivalent Series Resistance) should be low enough to minimize voltage ripple.
The TPS2383PM has an operating temperature range of -40°C to 125°C. However, the device's performance and reliability may degrade at temperatures above 85°C. It is recommended to ensure that the device operates at a temperature below 85°C for optimal performance and reliability.
The TPS2383PM has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The voltage divider network should be designed to trigger the OVP threshold voltage (typically around 12V) when the input voltage exceeds the maximum allowed value. The OVP pin can also be connected to a external voltage supervisor IC for more advanced OVP functionality.
The output capacitor value depends on the output voltage and ripple requirements. A general rule of thumb is to choose a capacitor with a capacitance value of at least 10uF and a voltage rating of at least 1.5 times the output voltage. Additionally, the capacitor's ESR should be low enough to minimize voltage ripple.
