Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LT8610EMSE is a compact, high-efficiency, high-speed synchronous single-chip buck switching regulator with transient current consumption as low as 2.5μA. All necessary circuits are equipped with top and bottom power switches to minimise the need for external components. The low-ripple burst mode maintains high efficiency at extremely low output currents while keeping output ripple below 10mVP-P. The SYNC pin supports synchronization to an external clock. The internal compensation using a peak current mode topology allows the use of small inductors, providing fast transient response and good loop stability. The EN/UV pin has a precise 1V threshold, which can be used to program VIN undervoltage lockout or shut down the LT8610EMSE, reducing the input power supply current to 1μA. During startup, the capacitance on the TR/SS pin can be used to program the output voltage slew rate. The PG flag signals when VOUT is within ±9% of the programmed output voltage or when a fault occurs.

The LT8610EMSE is available in a small 16-pin MSOP package with an exposed pad for low thermal resistance.

• 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.
