The recommended layout and placement for the TPS3510P involves placing the device close to the power source, using a solid ground plane, and keeping the input and output capacitors close to the device. A 4-layer PCB with a solid ground plane is recommended. Additionally, the device should be placed away from high-current carrying traces and noise sources.
To ensure stability, the TPS3510P requires a minimum output capacitance of 10uF, and the output capacitor should be placed close to the device. Additionally, the input capacitor should be at least 1uF and placed close to the input pin. The device should also be decoupled from the power source using a 1uF capacitor.
The TPS3510P can handle a maximum input voltage of 18V. However, it is recommended to operate the device within the recommended input voltage range of 2.7V to 15V for optimal performance and reliability.
The TPS3510P is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures to ensure reliable operation.
The output voltage of the TPS3510P can be calculated using the following formula: Vout = 1.22 x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network. The output voltage can be adjusted by changing the ratio of R1 and R2.
