TI recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to minimize thermal impedance. A thermal via array under the device can also improve heat dissipation.
Use a reliable communication protocol like I2C or SPI, and ensure proper signal termination, pull-up resistors, and clock synchronization. Also, implement error detection and correction mechanisms to handle data transmission errors.
Choose capacitors with low ESR, high ripple current rating, and a voltage rating that exceeds the maximum input voltage. X5R or X7R ceramic capacitors are recommended. Ensure the capacitors are placed close to the device and connected with short, low-inductance traces.
Follow a controlled power-up sequence, starting with the input voltage, then the enable signal, and finally the clock signal. During power-down, reverse this sequence. Ensure a soft-start or ramp-up of the input voltage to prevent inrush currents.
Keep the UCD9090 and its associated components away from noise-sensitive areas. Use a solid ground plane, and ensure that high-frequency signals are routed away from the device. Implement proper shielding, and use EMI filters or common-mode chokes if necessary.
