AD1674JRZ_AD22280 Introduction

Texas Instruments (TI) today introduced an ultra-low power switching regulator TPS62840, its operating quiescent current (IQ) can reach 60nA, only 1/3 of similar devices in the industry. In addition, the new DC/DC converters have a wide input voltage (VIN) range of 1.8V to 6.5V to support a variety of chemistries and configurations. It delivers very high light-load efficiency of 80% at 1-µA loads, enabling designers to extend the battery life of their systems or use fewer or smaller batteries to shrink their overall power solution size and reduce costs.

. According to IC Insights statistics, in the past 10 years (2009-2018), all 11-ball semiconductor manufacturers closed or rebuilt a total of 97 fabs. The details are shown in the figure below. Among them, 42 150mm fabs and 24 200mm fabs were closed, while the number of closed 300mm fabs accounted for only 10% of the total.

Active noise reduction ANC is to listen to the background noise, use the chip and algorithm model to calculate the noise sound wave and generate the anti-phase sound wave, and use the sound wave superposition and cancellation principle to achieve the noise reduction effect. . Throughout its development history, in the early 20th century, acoustic experts began to consider starting from the noise itself to achieve the purpose of reducing noise. Earlier in 1933, German physicist Paul Lueg proposed active noise control, that is, active noise reduction. concept, using the principle of destructive interference of sound waves to reduce noise.
