TPS54291PWP Frequently Asked Questions (FAQs)
The recommended input capacitor value is 10uF to 22uF, and the type should be a low-ESR ceramic capacitor, such as X5R or X7R, to ensure stable operation and minimize input voltage ripple.
To minimize EMI and noise, it is recommended to follow a star-ground configuration, keep the input and output capacitors close to the device, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW) away from sensitive nodes.
The maximum ambient temperature range for the TPS54291PWP is -40°C to 125°C. However, the device's performance and reliability may be affected at extreme temperatures, so it is recommended to operate within a range of -20°C to 85°C for optimal performance.
Yes, the TPS54291PWP is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive applications and is designed to meet the requirements of high-reliability systems.
The output voltage ripple can be calculated using the formula: ΔVout = (IL / (2 * fsw * Cout)) * (1 / (1 - (Vin / Vout))), where IL is the output current, fsw is the switching frequency, Cout is the output capacitor value, Vin is the input voltage, and Vout is the output voltage.
