Description:

The GD30MP1000 is an integrated solution for DDR5 SODIMM and UDIMM power management IC. The PMIC features three buck converters and two LDO regulators.The buck converters are designed by capacitor current sense constant on time (CCS COT) control that provides fast transient response, the noise immunity and all kinds of very low ESR output capacitor for ensuring

performance stabilization. All three buck converters equip with automatic power saving mode (PSM) for optimizing

efficiency. The two LDO regulators, VOUT_1.0V and VOUT_1.8V, can supply DIMM module's sideband and SDP usage. The PMIC supports selectable interface (I2C or I3C Basic) to fit various application environment.

Two of the buck converters (SWA and SWB) can beconfigured to operate in dual-phase single channel. TwoADCs are implemented to monitor the currentconsumptions of the buck converters and the voltageinformation of the input/output rails.The GD30MP1000 is available in low-profile thermalenhanced WQFN-28 (3.00 mmx4.00 mm) package.
