The recommended layout and placement for the TPS2561DRCR involves placing the device close to the load, using short and wide traces for power and ground, and keeping the input and output capacitors close to the device. A 4-layer PCB with a solid ground plane is recommended.
The input capacitor should have a low ESR and be rated for the input voltage. The output capacitor should be chosen based on the output voltage and current requirements. A general rule of thumb is to use a 10uF to 22uF ceramic capacitor for the input and a 10uF to 47uF ceramic capacitor for the output.
The maximum ambient temperature range for the TPS2561DRCR is -40°C to 85°C. However, the device can operate up to 125°C junction temperature.
The TPS2561DRCR has a built-in overcurrent protection feature that can be enabled by connecting the OCSET pin to a resistor divider network. The resistor values can be calculated based on the desired overcurrent threshold.
Yes, the TPS2561DRCR is qualified for automotive and high-reliability applications. It meets the requirements of the AEC-Q100 standard and is suitable for use in harsh environments.
