Texas Instruments provides a recommended PCB layout in the TPS2383APM datasheet, which includes guidelines for component placement, trace routing, and thermal management. Additionally, the TI Power Management Guide to Layout (SLUA271) provides general guidelines for power management ICs, including the TPS2383APM.
The inductor value selection depends on the input voltage, output voltage, and output current requirements. TI provides an inductor selection guide in the TPS2383APM datasheet, which includes a formula to calculate the inductor value. Additionally, online inductor selection tools, such as the TI Inductor Selection Tool, can help simplify the process.
The TPS2383APM has a maximum ambient temperature rating of 85°C (TJ = 150°C). However, the device's thermal performance can be affected by factors such as PCB layout, airflow, and thermal management. It's essential to consider these factors when designing the system to ensure reliable operation.
The TPS2383APM is a commercial-grade device, but it can be used in high-reliability or automotive applications with proper design, testing, and validation. TI provides additional resources, such as the TI Automotive Reliability Guide (SLLA271), to help designers ensure the device meets the required reliability and quality standards.
The TPS2383APM has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage source. The OVP threshold is set by an external resistor divider network. TI provides a detailed explanation of the OVP implementation in the TPS2383APM datasheet and application notes.
