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.
