Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8616EUDE is a high efficiency, high-speed, dual-channel, synchronous, monolithic, step-down switching regulator that consumes only 6.5μA of quiescent current with both channels enabled. Both channels contain all the switches and necessary circuitry to minimise the need for additional external components. Low-ripple burst mode operation allows high efficiency at very low output currents while minimising output ripple. A SYNC pin is used for synchronisation to an external clock. Internal compensation and peak current mode topologies allow the use of small inductors with fast transient response and excellent loop stability. The enable pin has an accurate 1V threshold and can be used to set undervoltage blocking, a capacitor on the TR/SS pin sets the rate of rise of the output voltage ramp during startup, and the PG pin signals when each output is within 10% of the programmed output voltage. the LT8616EUDE is available in a TSSOP package for high reliability.

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.
