The SY5888 is a power management IC (PMIC) for DDR5 SODIMM and UDIMM, and integrates three high efficiency Buck DC-DC converters, two LDOs, and flexible interface.
The device provides three channels buck outputs: SWA/SWB/SWC. SWA and SWB default are single phase and can be configured dual phase with current share operation.
VOUT_1.8V/VOUT_1.0V LDOs are intended to power supply SPD hub and Temp Sensor on DIMM. SY5888 is available FC-QFN28 3mmx4mm package, and is halogen and lead free, compliant with RoHS.
VIN/VIN_Bulk Supply Range: 4.25V to 5.5V
Three Buck Regulators: SWA (1 phase,default 1.1V,max 6A Valley)； 0.8V~2.2V，5mV/10mV step + offset； SWB (1 phase,default 1.1V, max 6A Valley); 0.8V~2.2V，5mV/10mV step + offset； SWC (1 phase,default 1.8V, max 2A Valley)；1.5V~2.135V，5mV step
