Infineon provides a recommended PCB layout in the application note AN-1123, which includes guidelines for thermal vias, copper thickness, and component placement to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, current, and frequency. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the maximum input voltage, and a capacitance value between 1uF to 10uF. Consult the application note AN-1123 for more detailed guidance.
The maximum allowed voltage drop across the internal MOSFETs is typically around 1.5V to 2V, depending on the operating conditions. Exceeding this voltage drop may lead to reduced efficiency, increased power losses, and potential damage to the IC.
To ensure EMC, follow the guidelines in the application note AN-1123, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a common-mode choke and a Y-capacitor to reduce EMI emissions.
The recommended operating temperature range for the ICE3AR2280CJZ is -40°C to 150°C. However, the IC can operate up to 175°C for short periods during startup or fault conditions.
