Maxim’s single-stage PoL module targets Google’s 48V datacentre rack power scheme

Maxim’s single-stage PoL module targets Google’s 48V datacentre rack power scheme

An ideal PUE figure is 1.00 (all input power used effectively) – these converters will get your scheme closer, Maxim says. With the most efficient data centres topping out at a PUE of 1.1, the next level of IT infrastructure optimisation (Maxim says) is to reduce conversion stages and its associated losses. While today’s two-stage power conversion (48V-to-12V-to-Load) is a common architecture, its efficiency has peaked at about 90%.

Maxim’s scalable, 48V solution addresses efficiency, density, and transient performance barriers by using integrated power and magnetics. The 48V single conversion to the PoL (48V-to-Load) eliminates one conversion loss and reduces distribution power loss by a factor of 16 in a rack implementation, compared with 12V architectures. The company adds that it “…has a high performance and flexible 48V integrated solution—consistent with what Google proposed this week at the Open Compute Project Summit—for hyperscale data centre customers to implement later this year.”
