As AI computing, industrial, and telecom power demands skyrocket for higher power and efficiency, Southchip is stepping up with a comprehensive AC-DC platform solution.
Anchored by the SC3270 digital combo PFC/LLC controller and paired with SC3530/SC3531 synchronous rectification ICs, this setup bridges the entire power path—from front-end boost and isolated high-frequency conversion to secondary-side rectification. It's a game-changing domestic hardware foundation that slashes peripheral complexity and safety risks while driving peak efficiency for next-gen AI servers.
The SC3270 serves as the digital brain of the platform, offering UART-programmable flexibility. Its PFC stage uses peak current control with direct MOS sampling to trim thermal buildup and dynamically toggle between CCM, QR, and DCM modes for optimal efficiency across all loads. For LLC control, internal resonant voltage synthesis ditches messy external feedback networks, saving board space and freeing up pins for redundant secondary OVP/UVP monitoring. Meanwhile, the secondary side relies on SC3530/SC3531 controllers featuring dual-channel gate drives and lightning-fast nanosecond shutoff. By swapping out old-school diodes for low-RDS(on) MOSFETs, it crushes conduction losses and easily satisfies the brutal uptime and efficiency standards of modern AI data centers.
This new PFC+LLC+SR ecosystem underscores Southchip's aggressive push into high-power computing and industrial power infrastructure. By fusing smart digital control with ultra-clean layouts and robust secondary rectification, it tackles legacy thermal and space constraints head-on. As AI and edge computing expansion hits overdrive, modular, high-efficiency architectures like this will become the baseline blueprint for green, high-density power delivery.
