Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8390HUFD is a synchronous 4-switch buck-boost DC/DC controller. The output voltage, input or output current can be adjusted above, below or equal to the input voltage. A proprietary peak buck/peak boost current mode control scheme enables tunable and synchronous 150kHz to 650kHz fixed frequency operation, or internal ±15% delta spread spectrum frequency modulation to reduce EMI. Input voltages range from 4V to 60V and output voltages range from 0V to 60V, with seamless low-noise transitions between operating regions.

Applications

● Automotive, industrial, telecommunication systems

● High-power battery-powered systems

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
