Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC7878AUH is a high performance buck-boost switching regulator controller that operates at input voltages above, below, or equal to the output voltage. The constant frequency, peak current mode architecture allows for phase-locked switching frequencies up to 600kHz, and the programmable input or output current loops precisely regulate the average input or output current to support battery charging applications. With a wide 5V to 70V input and output range and seamless low noise transitions between operating areas, the LTC7878 is ideal for industrial and telecom systems.

Applications

● Industrial and telecoms systems

● Distributed DC power or battery 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?
