Southchip Releases High-Performance Piezo Fan Driver
Southchip unveils next-generation fully integrated buck-boost charger
Southchip launches its next-generation fully integrated dual-input, bidirectional synchronous buck-boost charger SC8984. In forward charging mode, it supports up to 22V input voltage and 5A charging current. In reverse discharging (OTG) mode, it delivers a wide 3V-22V output voltage range and up to 5A output current. The chip is specifically optimized for 2- to 4-cell Li-ion battery applications and adopts Southchip's proprietary ACOT (Adaptive Constant-On/Off-Time) valley/peak control technology to improve system transient response. It provides a more efficient and flexible charging solution for high-end consumer electronics such as multi-cell tablets, smartphones, drones, smart speakers, POS terminals, and professional medical devices.
Southchip launches audio power amplifier, defining an immersive acoustic experience
Southchip unveiled its new audio power amplifier series, including the 10.5V SC28561 and the 9.5V SC28376. These products are designed to flexibly meet the audio voltage requirements of smartphones across different quality and price segments. The series features ultra-low standby power consumption and high power conversion efficiency, significantly extending the audio playback time of smartphones. Specifically, SC28561 achieves a standby power consumption as low as 9.1mW, a 43.7% reduction compared to similar products. At the common 1W power level, its power conversion efficiency reaches up to 90.5%, and its UVLO threshold is as low as 1.7V, aligning with the development trend of silicon anode batteries. This delivers a powerful, pure, and long-lasting audio experience for users, marking Southchip's strategic expansion into the acoustic market.
