Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LM22676QMRE-ADJ/NOPB switching regulator provides all the features needed to achieve a highly efficient high-voltage buck regulator with a minimum of external components. The regulator is easy to use and integrates a 42V N-channel metal-oxide-semiconductor field-effect transistor (MOSFET) switch to provide up to 3A of load current. It features excellent line and load regulation and high efficiency (>90%). Voltage mode control provides a short minimum turn-on time, resulting in the widest ratio between input and output voltages. Internal loop compensation means that the user does not have the tedious task of calculating loop compensation components. The regulators are available in both 5V fixed output and adjustable output voltage options. The 500kHz switching frequency allows the use of small external components and good transient response. A precision enable input simplifies regulator control and system power sequencing. In shutdown mode, the regulator current consumption is only 25μA (typical). The built-in soft-start function (500µs typical) saves external components, and the LM22676QMRE-ADJ/NOPB also has built-in thermal shutdown and current limiting to protect the device from unintentional overload.

• 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.
