Hangzhou Silan Microelectronics 

Hangzhou Silan Microelectronics Co., Ltd., a Chinese firm founded in 1997 and based in Hangzhou, specializes in the design, manufacture, and sale of integrated circuits (ICs). Its extensive product lineup features microcontrollers (MCUs) and a variety of power management components, including AC-DC and DC-DC converters. The company also develops a broad spectrum of LED drivers—such as constant-current, linear, isolated, and non-isolated types—along with high and low voltage motor driver modules and gate drivers. For audio applications, Silan offers power amplifiers, headphone drivers, volume and sound effect control circuits, and components for AM/FM radio tuners and demodulators. Its optical storage solutions encompass CD/DVD pick-up and servo decoding ICs, in addition to digital audio system-on-chip (SOC) circuits. The company further supplies drivers for VFD, LCD, and LED display panels, electronic fan control units, telephone circuits, high-frequency heads, remote control encoders/decoders, and low-dropout regulators. A key segment of its portfolio is dedicated to MEMS sensors, which include accelerometers, inertial modules, geomagnetic sensors, ambient light (ALS) and proximity (PS) sensors, VCSELs, heart rate sensors, and silicon microphones. Moreover, it provides measurement ICs, such as multi-meter circuits, and a range of discrete semiconductor devices, including transistors, diodes, MOSFETs, and integrated modules. These versatile components are utilized across numerous sectors, including LED displays, industrial systems, audio-visual equipment, consumer electronics, automotive applications, toys, LED lighting solutions, and household appliances.
