Samsung Electronics, a world leader in advanced semiconductor technology, today announced the industry's first integrated power management ICs (PMICs) — S2FPD01, S2FPD02 and S2FPC01, for the fifth-generation double data rate (DDR5) dual in-line memory module (DIMM). One major design improvement to the newest generation DRAM solution involves integrating the PMIC into the memory module — previous generations placed the PMIC on the motherboard — offering increased compatibility and signal integrity, and providing a more reliable and sustained performance.

For improved performance efficiency and load-transient responses, Samsung's new PMICs for DDR5 modules have been equipped with a high-efficiency hybrid gate driver and a proprietary control design (asynchronous-based dual-phase buck control scheme). This scheme allows the DC voltage to step down from high to low with a fast transient response to changes in the output load current and adapts the conversion accordingly to efficiently regulate its output voltage at near-constant levels. The control scheme also features both pulse width and pulse frequency modulation methods, preventing delays and malfunctions when switching modes.
