Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8277RUDCM is a two-phase, constant-frequency, current-mode boost and SEPIC controller that drives N-channel power MOSFETs. two-phase interleaved operation reduces system filter capacitance requirements. An internal LDO regulator draws power from VIN or VOUT to provide a 5V supply to the gate driver. The fixed-frequency, current-mode architecture provides stable operation over a wide range of supply and output voltages. The operating frequency can be set from 100kHz to 2MHz with an external resistor or synchronised to an external clock using the SYNC pin.

Applications

● Automotive, telecom and industrial power supplies

• 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.
