A good layout practice is to keep the input and output capacitors close to the device, use a solid ground plane, and keep the power traces short and wide. Additionally, it's recommended to use a Kelvin connection for the sense pins to minimize noise and ensure accurate voltage sensing.
The input capacitor should be a low-ESR ceramic capacitor with a value between 1uF to 10uF, while the output capacitor should be a low-ESR ceramic or tantalum capacitor with a value between 10uF to 100uF. The capacitor values and types should be chosen based on the specific application requirements, such as output voltage, current, and ripple requirements.
The TPS3510DRG4 has an absolute maximum input voltage rating of 18V. However, the recommended maximum input voltage is 15V to ensure proper operation and to prevent damage to the device.
The output voltage of the TPS3510DRG4 can be adjusted by using a resistive divider network between the output and the sense pins. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
The typical startup time for the TPS3510DRG4 is around 1ms to 2ms, depending on the input voltage, output voltage, and load conditions. However, this time can vary depending on the specific application and design.
