A good PCB layout for the EC103D1,116 involves keeping the input and output tracks separate, using a solid ground plane, and minimizing track lengths and widths to reduce parasitic inductance and capacitance. Additionally, it's recommended to place decoupling capacitors close to the device and use a common mode choke to filter out high-frequency noise.
The EC103D1,116 requires a single 3.3V power supply, and it's essential to ensure a clean and stable power source. Power sequencing is not critical, but it's recommended to power up the device after the input voltage has stabilized. A soft-start circuit can be used to reduce inrush current and prevent voltage drops during power-up.
The EC103D1,116 can tolerate an input voltage ripple of up to 100mV peak-to-peak. Exceeding this limit may affect the device's performance and stability. It's recommended to use a high-quality input filter or a voltage regulator to minimize voltage ripple and ensure reliable operation.
To minimize EMI emissions, it's recommended to use a shielded enclosure, keep the device away from noise sources, and use a common mode choke to filter out high-frequency noise. Additionally, ensure that the PCB layout is optimized for EMI reduction, and use a low-pass filter on the output to reduce high-frequency harmonics.
The EC103D1,116 has a maximum junction temperature of 150°C. To ensure reliable operation, it's essential to provide adequate heat sinking, such as a thermal pad or a heat sink, and ensure good airflow around the device. The device's thermal resistance (RthJA) is 30°C/W, and the maximum power dissipation is 1.5W.
