Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20003ATPB/V are small synchronous buck converters with integrated high-side and low-side MOSFETs. each device is designed to deliver up to 2A/3A output at input voltages from 3.5V to 36V while using only 15µA quiescent current. Voltage quality can be monitored by observing the PGOOD signal. The device operates at 98% duty cycle, making it ideal for automotive applications. the MAX20003ATPB/V provides a fixed output voltage of 5V/3.3V and a programmable output voltage from 1V to 10V. the frequency is programmable via the FOSC pin. Frequency is programmable through a ground resistor on the FOSC pin. the FOSC pin has a ground resistor on the FOSC pin that allows the frequency to be programmed from 220kHz to 2.2MHz. the MAX20003ATPB/V offer strong frequency setting and frequency hopping modes, and have an ultra-low quiescent voltage mode with ultra-low quiescent current of 15µA. the MAX20003ATPB/V have pins that can be programmed to open. They have pins that can be programmed to turn on/off spread spectrum mode, which can be programmed to turn on/off spread spectrum to further help system designers achieve better. the MAX20003ATPB/V are available in a small 5mm x 5mm 20-pin TQF package with exposed pads and use very few external components.

● Navigation and radio hosts

• 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.
