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.
To minimize noise and EMI, it's essential to follow a good layout practice, such as keeping the input and output capacitors close to the device, using a solid ground plane, and separating the input and output traces. Additionally, use a shielded inductor and orient it to minimize radiation.
The TPS60243DGKR can deliver up to 200mA of output current, but it's recommended to derate the output current based on the ambient temperature and the device's thermal performance to ensure reliable operation.
Yes, the TPS60243DGKR is suitable for battery-powered devices due to its low quiescent current (IQ) of 15uA, which helps to extend battery life. However, it's essential to consider the device's shutdown current and ensure that it meets the system's power-down requirements.
To ensure output voltage accuracy and stability, it's recommended to use a high-precision resistor divider network for the feedback resistors (RFBT and RFBG) and to minimize the noise on the FB pin. Additionally, use a low-ESR output capacitor to filter out high-frequency noise.
