Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8637EV synchronous buck regulator features a quiet switcher architecture designed to minimise EMI emissions while providing high efficiency at high switching frequencies. Peak current mode control with a minimum on-time of 30ns enables high step-down ratios even at high switching frequencies.The LT8637EV's ultra-low 2.5µA quiescent current (with outputs fully regulated) enables applications requiring maximum efficiency at very low load currents.The LT8637EV features external compensation for current sharing at high switching frequencies and Fast Transient Response Fast transient response at high switching frequencies. Burst mode operation for ultra-low standby current consumption, forced continuous mode to control frequency harmonics across the LT8637EV, or spread spectrum operation to further reduce EMI emissions. Soft-start and tracking functions are available through the soft-start and tracking functions are accessible through the TR/SS pin, with precise input voltage UVLO thresholds.

Applications

• Automotive and Industrial Goods

• General Purpose Buck

• 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?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
