Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20019ATBC/V is a 2.2MHz and 3.2MHz dual buck converter with integrated high-side and low-side MOSFETs. buck converter with integrated high-side and low-side MOSFETs. the high-voltage buck converter is capable of continuous operation at input voltages up to 17 V. The output voltage is factory preset. The output voltage is factory preset. Buck 1 is preset to 3.3V, 3.0V, or 2.8V. Buck 2 is preset to 1.8V, 1.5V, 1.2V, or 1V. Another option is to preset 5V for Buck 1 and 3.3V for Buck 2. The low voltage buck operates in a fixed-frequency PWM mode, with a switching frequency of either 2.2MHz or 3.2MHz. The high-frequency operation allows for a fully ceramic capacitor design and small external components. Low resistance on-chip switching ensures high efficiency while minimising critical inductance. 500mV enabled hysteresis on the MAX20019ATBC/V allows the use of long, low-cost coaxial cables, even at slow speeds. Long, low-cost coaxial cables can be used even in slow startup situations. buck 1 on the MAX20019ATBC/V starts after VSUP is greater than 5.5V and buck 1 is driven by the EN input.

Applications

● Surround View Camera Power Supplies

● Automotive 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.
