The RT5128A is a multi-output integrated circuit (MOIC) designed for use with Intel MTL-UPH and AMD SVI3 mobile CPU platforms. The RT5128A integrates two buck controllers, four buck converters, and one load switch. Furthermore, the RT5128A supports both DDR5 and LPDDR5 applications.To prevent abnormal operation or electrical overstress, the RT5128A features UVLO, OVP, UVP, OTP, and overcurrent-limit protections for each rail. The RT5128A is available in a UQFN-42L 5x5 (FC) package.
