Samsung released new power management solutions for DDR5 modules
Samsung announced the launch of the industry’s first integrated power management IC (PMIC) for the new generation of DDR5 memory, namely S2FPD01, S2FPD02, and S2FPC01. In the latest generation of DRAM solutions, one of the major improvements is the integration of PMIC into the memory module (previously placed on the motherboard), which can provide higher compatibility and signal integrity, and more reliable and longer-lasting performance.
In order to improve efficiency and load transient response, Samsung power management solutions for DDR5 modules are equipped with an efficient hybrid gate driver and a dedicated control design. This solution allows the DC voltage to be output with a fast transient response and can adjust the conversion accordingly to the change of the load current, so as to effectively adjust the output voltage to a near-constant level. At the same time, the control scheme also has pulse width and pulse frequency modulation methods to prevent possible delays and failures when switching modes.
Among the three integrated power management ICs for DDR5 memory, S2FPD01 and S2FPD02 are for data centers and enterprise servers that need to perform heavy analysis tasks, machine and deep learning, artificial intelligence, and various other computing tasks to provide the best performance.
The slight difference is that S2FPD01 is designed for low-density modules, while S2FPD02 is designed for high-density modules. Samsung’s new PMICs can operate at up to 91-percent power efficiency.
For ordinary consumers, they are more likely to encounter S2FPC01 in the future, because this solution is specially designed for desktop and notebook computers and is manufactured using a 90nm process node to provide better performance in a smaller package.
At present, Samsung’s S2FPD01, S2FPD02, and S2FPC01 three DDR5 memory integrated power management ICs have provided samples to customers.
