Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8357JMSE is a wide input range, current-mode, DC/DC controller that can be configured as a boost, SEPIC, or flyback converter. The LT8357 can drive low-side N-channel power MOSFETs with a 5V split-gate drive.The current-mode architecture supports either an adjustable and synchronisable 100kHz to 2MHz fixed-frequency mode of operation or an internal 19% delta spread spectrum mode of operation for reduced The current mode architecture supports adjustable and synchronisable 100kHz to 2MHz fixed frequency operation or internal 19% delta spread spectrum operation for reduced EMI. Pulse hopping mode or low ripple burst operation can be selected at light loads. Other features include good output power and output short circuit protection in SEPIC and flyback configurations.

• 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?
