Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20049CATEA/VY are dual step-down converter ICs with two low dropout regulators (LDOs) that provide a single-chip solution for automotive cameras. The two buck converter designs operate in fixed frequency PWM mode with input voltages of 5V to 17V for the MAX20049, 4V to 17V for the MAX20049C, and 3.5V to 17V for the MAX20049D. Dedicated high-voltage inputs allow for flexible solutions.

The ICs provide voltage monitoring of all four output voltage rails. The power supply pulls down when an overvoltage or undervoltage is detected. To support long and inexpensive coaxial cables, the devices have 500mV SUP1 hysteresis. Both buck converters offer very short on-time and allow the use of a 17V input to produce a 0.9V output. High frequency operation allows the use of an all ceramic capacitor design, as well as small external components. Low resistance on-chip switches ensure high efficiency while minimising critical inductance.

Point-of-load

• 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.
