Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20408AFOF/VY are automotive high-integrity synchronous buck converters with internal high-side and low-side switches. These ICs have input voltages from 3.0V to 36V and output currents up to 8A/10A with input voltages from 3.0V to 36V. Voltage quality can be monitored with the PGOOD signal. the MAX20408AFOF/VY can operate in differential mode with a duty cycle of 99%, making it well suited for automotive and industrial applications. the MAX20408AFOF/VY is available with programmable or fixed output voltage options. Output Voltage Options. High switching frequency options of 2.1MHz and 400kHz allow the use of smaller external components, reduce output ripple, and ensure no AM interference.SYNC input programmability enables three forced PWM modes, frequency hopping modes with ultra-low quiescent currents, and synchronisation with an external clock. The spread spectrum option minimises EMI emissions.

• 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.
