ETI Systems recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the input and output stages. Additionally, keep the input and output traces as short as possible and use a common mode choke to reduce EMI.
Make sure to provide adequate heat sinking and airflow around the device. ETI Systems recommends a minimum of 10mm clearance around the device for airflow, and a heat sink with a thermal resistance of 10°C/W or less.
The maximum allowable voltage drop is 1V for the input and 0.5V for the output. Exceeding these values may affect the device's performance and reliability.
Yes, but it's not recommended. The MW22B-3-5K is designed to operate as a single device, and paralleling multiple units may lead to instability and reduced reliability. If higher power is required, consider using a different device or consulting with ETI Systems' application engineers.
The typical start-up time for the MW22B-3-5K is around 10ms, but this can vary depending on the input voltage, output load, and other factors. Consult the datasheet for more information.
