TP7661BDC-DC Converter

TP7661B DC-DC Converter

Product introduction

The TP7661 CMOS DC-DC converter is a low-power, easy-to-operate power chip. Double voltage use method: input negative voltage

When -1.0~-8.0V, it can generate -2.0~ -16V output; when input positive voltage is 1.0~ 8.0V, it can generate -1.0~ -8.0V output triple voltage

How to use: Input negative voltage -1.0~-6.0V, it can produce -3.0~ -18.0V output, input positive voltage 1.0~ 6.0V can produce -2.0~ -12.0V

output. Three temperature gradient adjustment voltages are available. The PIN pin is compatible with SCI7661. (The performance of TP7661B is the same as that of TP7661A except that it has no Vreg and RV functions, and its PIN pin is compatible with SCI7661)

Hong Kong Xinrui guarantees original imported spot

The U.S. Department of Commerce recently announced that it plans to include artificial intelligence and other emerging high-tech technologies on the export control list. That has clouded the prospects of some U.S. tech companies and has many industry experts worried. The U.S. Department of Commerce's Bureau of Industry and Security listed 14 "representative emerging technologies" that the U.S. government proposed to regulate on the 19th, covering artificial intelligence, microprocessor technology, advanced computing technology, robotics, 3D printing, quantum information, advanced materials and biotechnology.

The list is now open for 30-day public comment.

According to a document released by the U.S. Department of Commerce, the Bureau of Industry and Security supervises the export of dual-use and less sensitive military products, mainly screening exports involving national security and high-tech areas, but many emerging technologies have not been included in the list. The list seeks to identify emerging and foundational technologies "essential to U.S. national security."

Industry insiders believe that a large number of American technology companies will be adversely affected if they are regulated according to this list. For example, related technologies used in Apple's artificial intelligence voice assistant Siri, face recognition, etc. are all within the scope of control. Shares of a number of U.S. tech companies fell after the list was released. On the 20th, Apple closed down 4.78%, and memory chip maker Micron Technology fell about 2%.

Richard Massini III, a lawyer at Washington High Winning Law Firm, told the media that the new export control will bring great changes to the technology field. Many technology companies such as biotechnology companies that have never been subject to similar controls in history will be They will be constrained in terms of financing, foreign technical cooperation and product exports.

Daniel Castro, vice chairman of the Information Technology and Innovation Foundation, an American think tank, said that if the United States bans the export of artificial intelligence technology, other countries will fight back, which means that American companies cannot enter certain markets, but will allow other countries to company is unimpeded.

The new measures are aimed at maintaining U.S. technological leadership by strictly limiting access to emerging and critical U.S. technologies by foreign companies and investors. But Castro argues that implementing the measure could backfire, for example by hampering the international cooperation needed to develop emerging technologies such as artificial intelligence.

Lucas Wilson, an artificial intelligence researcher at Dell in the United States, posted on social media that the development of artificial intelligence technologies such as neural networks, deep learning and genetic algorithms relies on open source research, and export control on this will only make the United States give up on artificial intelligence. status in the field.

Ben Hilborn, a researcher at Deepsig, an artificial intelligence firm in Virginia, called the policy “AI nationalism,” which he believes shows policymakers have little or no respect for technology and science.

Hilborn said export controls were "wrong and ineffective," severely undermining the capabilities of U.S.-based researchers and doing nothing to protect U.S. interests. TP7661ATP7661ATP7661A

Brandon Dolan-Gavitt, an associate professor of computer science at New York University, agrees, saying the practice has been "incredibly stupid" since the 1990s, and it's not much better this time around. TP7661A TTP7661AP7661A

Mark Delora, a video game expert who served as a senior adviser on digital media to the Obama administration, quipped that it felt unreasonable to have encryption and high-performance computing export restrictions on his gamepad. TP7661A/TP7661A/
