Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20003CATPB/V are small, synchronous buck converters with integrated high-side and low-side MOSFETs. Each device is designed to deliver up to 2A/3A with input voltages from 3.5V to 36V, while using only 15µA quiescent current at no load. Voltage quality can be monitored by observing the PGOOD signal. The devices can operate in dropout by running at 98% duty cycle, making them ideal for automotive applications. 

The devices offer fixed output voltages of 3.3V, along with the ability to program the output voltage between 1V to 10V. Frequency can be programmed using a resistor to ground on the FOSC pin from 220kHz to 2.2MHz. The devices offer a forced fixed-frequency mode and skip mode with ultra-low quiescent current of 15µA. They have a pin that can be programmed to turn on/off the spread spectrum, further helping systems designers with better EMC management. 

The MAX20003CATPB/V are available in a small 5mm x 5mm 20-pin TQFN package with exposed pad and use very few external components.

• 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.
