Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8615RUDM is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that can deliver 3.5A of continuous current. The LT8615’s ultralow 2.5μA quiescent current in Burst Mode operation (with the output in full regulation) enables high efficiency down to very low load currents while keeping the output ripple below 10mVP-P.

A SYNC pin allows synchronization to an external clock or spread-spectrum modulation for low EMI operation. Internal compensation with peak current-mode topology allows the use of small inductors and results in fast transient response and good loop stability. The EN/UV pin has an accurate 1V threshold and can be used to program VIN UVLO or to shut down the part. A capacitor on the TR/SS pin programs the output voltage ramp rate during start-up. An open-drain PG pin flag signals when the output is within ±8% as well as fault conditions.

Applications Of LT8615RUDM

Automotive and Industrial Supplies

Low EMI Step-Down

• 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.
