Southchip’s latest innovation, the SC8723, is a game-changer in power management. Identified by the team at ChargerLAB, this synchronous buck-boost converter features a 4-switch architecture with integrated MOSFETs, allowing for smooth voltage conversion across a wide 2.7V–22V input range. Capable of handling up to 10A inductor current, this chip is designed to maximize performance while minimizing space. Its track record is already impressive, with successful integrations in premium hardware like the OnePlus 45W liquid cooler and Baseus Tesla docks.
The SC8723 is all about flexibility and safety. It supports multiple switching frequencies (250kHz, 500kHz, and 800kHz) and offers both PWM and PSM modes to balance power needs between high performance and standby efficiency. Safety is built into its compact QFN22 package, featuring comprehensive protections against voltage spikes, short circuits, and overheating. With programmable current limits and soft-start technology, it provides developers with a reliable, ready-to-use solution for complex power requirements.
The SC8723 is a perfect match for the evolving USB-C landscape. By integrating four MOSFETs directly into the chip, Southchip has helped designers reclaim valuable PCB real estate, making it an essential component for power banks, wireless chargers, and smart hubs. For manufacturers, the SC8723 means faster time-to-market and more compact, feature-rich products. It is truly an enabler for the next generation of portable, high-performance fast-charging accessories.
