FR9801S6CTR Step-Down Synchronous Rectifier Regulator, Input Voltage 4.5V to 21V

The FR9801S6CTR is a step-down synchronous rectifier regulator with an input voltage range of 4.5V to 21V and a 2A load capability. Current-mode control provides good transient response and single-cycle current limiting. The adjustable soft-start time can avoid the inrush current at the moment of turning on. In standby mode, the input current is less than 1uA. FR9801S6CTR is packaged in SOt23-6, which provides a compact system power solution with few external components, features, input voltage range: 4.5V to 21V, output voltage range: 0.8 to 17.85V, output current: 3.5A, switching frequency : 600KHZ, efficiency up to 94%_, adjustable soft-start time, low ESR ceramic capacitors are used in the periphery to ensure stable operation, over-temperature protection function can be automatically restored, with under-voltage protection function, package: SOT23-6, application , Discrete power system, network system, FPGA, DSP, ASIC power supply, green electronic products, notebook computer

With the 2019 version of OLED TVs, the company plans to increase the ratio of OLED TVs to total TV sales to 25% this year. In addition, LG Electronics expects the release of 8K OLED TVs and rollable TV models in the second half of the year to drive sales of OLED TVs.

LG Electronics held a launch ceremony for the 2019 edition of its high-end TV lineup at the LG Tech Park in Seoul on March 6. "OLED TVs accounted for a little over 20 percent of total TV sales last year," Kwon Bong-seok, president of LG Electronics' mobile communications and home entertainment division, said in a news release. "Our goal is to increase that to 25 percent this year. ."

As a first step toward boosting sales, LG Electronics lowered the price of new OLED TVs by 30 percent. The company has confirmed the price of 18 million won (about $15,946) for the 77-inch model OLED TV, down by 6 million won ($5,315). The largest 77-inch OLED model will be launched at a price of 12 million won to 18 million won ($10,633 to $15,946), while the 65-inch model will be priced between 5.2 million won and 8.9 million won ($4,607 USD to 7884). Prices for the 55-inch OLED TV range from 2.7 million won to 3.1 million won ($2,392 to $2,746).

LG Electronics has also beefed up the TV itself, with the second-generation Alpha 9 processor, which will be featured in its 2019 TV models, processing 2x faster than the first-generation processor, delivering more vibrant colors, plus , it can also analyze the original content to remove noise and "upmix" two-channel audio to 5.1 surround sound.

In addition, LG Electronics has installed the "AI Home Board" function in its latest TV models so that users can control other smart home appliances such as dryers, air conditioners and air purifiers through the TV remote control. For example, users can check the level of fine dust concentration on the AI Home Board and use the TV remote to turn on the air purifier while watching TV.
