Shanghai Wells Semiconductor Co., Ltd. is a semiconductor device design and sales company with independent R&D. The company was established in May 2007 and its headquarters is located in Shanghai Zhangjiang Hi-Tech Park.The main products include protection devices (TVS, TSS), power devices (MOSFET, Schottky Diode, Transistor), power management devices (Charger, LDO, Buck, Boost, Backlight LED Driver, Flash LED Driver), and four analog switches,which are widely used in mobile phones, computers, television, communications, security, automotive, wear, medical and other fields.
Linear Technology Corporation, a subsidiary of Analog Devices, Inc. (ADI), introduced the LT8609S, a 2A (3A peak), 42V input synchronous step-down switching regulator. Its unique Silent Switcher® 2 architecture utilizes two internal input capacitors and internal BST and INTVCC capacitors to minimize thermal loop area. The LT8609S is designed to significantly reduce EMI/EMC emissions due to the extremely well-controlled switching edges, with an internal ground plane and copper posts instead of bond wires.
Recently, Vishay Intertechnology, Inc. announced the launch of a new high sensitivity proximity and ambient light sensor - VCNL4200. The sensor uses FiltronTM technology with a detection range of up to 1.5 meters and is available in a small 8mm x 3mm x 1.8mm surface mount package. The Vishay Semiconductors VCNL4200 3-in-1 sensor features a high-power infrared emitter, proximity and ambient light photodetectors, a signal processing IC, and a 12-bit/16-bit ADC. It also provides an interrupt function and supports an I2C bus communication interface for smart homes. Industrial and office products.
