The recommended input capacitor value is 1uF to 10uF, and the type should be a low-ESR ceramic capacitor, such as X5R or X7R, to ensure stable operation and minimize noise.
Follow the recommended PCB layout guidelines in the datasheet, keeping the input and output capacitors close to the device, and using a solid ground plane to reduce noise and EMI. Also, avoid routing sensitive signals near the inductor and ensure a clear return path for the high-frequency currents.
The maximum ambient temperature range for the TPS60313DGSR is -40°C to 85°C, but the device can operate up to 125°C with derating. Refer to the thermal derating curve in the datasheet for more information.
Yes, the TPS60313DGSR is suitable for battery-powered devices due to its low quiescent current (IQ) of 15uA, which helps to extend battery life. However, ensure that the input voltage is within the recommended range and that the device is properly bypassed to minimize noise and voltage drops.
The output voltage of the TPS60313DGSR is set by the resistor divider network (R1 and R2) connected to the FB pin. Use the formula: VOUT = 1.2V x (1 + R2/R1) to calculate the output voltage. Ensure that the resistors are of high precision and low tolerance to maintain accurate output voltage regulation.
