Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20040DATPA/VY is a family of small synchronous buck-boost converters with integrated high-side and low-side switches.The MAX20040DATPA/VY can deliver up to 1.2A at input voltages from 2V to 36V while using only 52µA of quiescent current. The ICs provide output voltage accuracy of ±2%. Voltage quality can be monitored by observing the PGOOD signal.The MAX20040DATPA/VY has a fixed output voltage of 5V and a programmable range of 4.0V to 15V. See the Ordering Information sheet for more information. Frequency adjustable from 220kHz to 2.2MHz, enabling small external components Frequency adjustable from 220kHz to 2.2MHz, allowing the use of smaller external components, reducing output ripple, and ensuring no AM interference The frequency-hopping mode of the MAX20040DATPA/VY has a low quiescent current of 52µA. The MAX20040DATPA/VY ICs offer a frequency hopping mode with a low quiescent current of 52μA. These ICs can use spread spectrum frequency modulation to minimise EMI emissions caused by the modulation frequency.

• 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.
