A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to ensure good heat dissipation.
Use a shielded enclosure, keep the device away from antennas and high-frequency circuits, and ensure proper grounding and decoupling. Follow Infineon's EMC guidelines for more information.
The maximum allowed voltage on the VIN pin is 30V, but it's recommended to keep it below 28V for optimal reliability and performance.
The ICE3BS03LJGXUMA1 has built-in OVP and UVP. For OVP, the device will shut down if the input voltage exceeds 30V. For UVP, the device will shut down if the input voltage falls below 2.5V.
A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for the input capacitor. The capacitor should be placed as close to the VIN pin as possible.
