Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20343BEWE is an ultra-low quiescent current, in-phase boost/buck converter with 1A @ 3.5V current drive capability for applications requiring long runtimes with high burst currents. The devices feature a proprietary control algorithm that smoothly switches between buck, boost/buck, and step-up modes to minimize output voltage ripple discontinuities and sub-harmonics. 1.9V low start-up input voltage allows users to power the devices from a variety of sources, and the near-zero minimum operating voltage allows users to take full advantage of the energy efficiency. The MAX20343BEWE is also designed to minimize inductance and output capacitance requirements for space-constrained applications.

The MAX20343BEWE supports a highly configurable I2C serial interface or a fixed-setting version with single-pin support. The device operates over the -40°C to +85°C temperature range and is available in a 16-ball, 1.77mm x 2.01mm, 0.4mm pitch WLP package.

• 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.
