Samsung has launched its integrated power management ICs (PMICs) – S2FPD01, S2FPD02 and S2FPC01, for the fifth-generation double data rate (DDR5) dual in-line memory module (DIMM). The S2FPD01 and the S2FPD02 would offer optimal performance for today’s data center and enterprise servers that must run heavy analytics, machine and deep learning, and other various computing tasks in real time.
The FPD01 is designed for modules with low density; FPD02 for higher density.
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 would allow 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.
Server Power Efficiency
“With enhanced power efficiency and low output ripple voltage, the new PMICs S2FPD01 and S2FPD02 allow data centers and enterprise servers to take full advantage of their DDR5 performance for highly demanding, memory-intensive tasks,” said Harry Cho, vice president of System LSI marketing at Samsung Electronics.
By implementing a high-efficiency hybrid gate driver instead of a linear regulator, Samsung’s new PMICs can operate at up to 91-percent power efficiency.
Samsung’s DDR5 DIMM power management ICs, the S2FPD01 and S2FPD02 are currently being sampled to customers.
