Selection Guidance

When selecting the XDPE152C4D-IT72, verify the required phase count and current capability for your specific load. The device is optimized for multi-phase buck converters and requires external power stages (e.g., Infineon Smart Power Stages). Confirm PMBus/AVSBus compatibility with your system management firmware. For detailed electrical specifications, refer to the official datasheet as some parameters (e.g., PWM frequency, accuracy) are to be verified.
