The placement of the input capacitors C4, C5, and C6 relative to VIN and PGND pins of CSD88599Q5DC device should have the highest priority during the component placement routine. It is critical to minimize the VIN to GND parasitic loop inductance. A shunt resistor R21 is used between all three U4, U5, and U6 power block source terminals to the input supply GND return pin.

Input RMS current filtering is achieved via two bulk caps C17 and C18. Based on the RMS current ratings, the recommended part number for input bulk is CAP AL, 330 µF, 63 V, ±20%, PN: EMVA630ADA331MKG5S.
