The recommended layout and placement for the TPS3702AX18DDCT can be found in the Texas Instruments application note 'TPS3702 Layout and Placement Guidelines' (SLVAE04). It provides guidance on component placement, routing, and thermal considerations to ensure optimal performance and reliability.
The output voltage of the TPS3702AX18DDCT can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.8V), R1 is the resistance between the VOUT and FB pins, and R2 is the resistance between the FB pin and GND. The datasheet provides a detailed example of how to calculate the output voltage.
The maximum input voltage that the TPS3702AX18DDCT can handle is 24V. However, it's recommended to operate the device within the specified input voltage range (4.5V to 18V) to ensure optimal performance and reliability.
To ensure the TPS3702AX18DDCT is stable and doesn't oscillate, it's essential to follow the recommended layout and placement guidelines, use a sufficient output capacitor (at least 10uF), and ensure that the input voltage is within the specified range. Additionally, the datasheet provides guidance on selecting the correct output capacitor and input filter components to prevent oscillation.
The thermal shutdown temperature of the TPS3702AX18DDCT is typically around 150°C. When the device exceeds this temperature, it will shut down to prevent damage. The device will automatically restart when the temperature drops below 130°C.
