Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20429AAFNA/VY is a high-efficiency dual switching regulator that provides up to 6A (peak) of load current per output. From 0.5V to 1.5875V in 12.5mV steps and from 1.6V to 3.8V in 50mV steps. In 50mV steps. The ICs operate from 3V to 5.5V, making them ideal for on-board point-to-point applications. Making it ideal for on-board point-of-load and post regulation applications. With a total output error at load of less than ±1.0%, the MAX20429AAFNA/VY operates in a fixed-frequency PWM mode with a switching frequency of 2.1 MHz or 3.2 MHz. The high-frequency operation allows for an all-ceramic capacitor design and small external components. Low resistance on-chip switching ensures high efficiency at heavy loads while minimising critical inductance and making layout work much simpler than discrete solutions. Following a simple layout and footprint ensures that new designs are successful from the outset. the MAX20429AAFNA/VY features MAXQ™ technology, which provides accurate transient performance and phase margins. This enables maximum power, performance, and accuracy configurations to be obtained from the converter in a very short period of time.

Applications

● Secondary regulators for SoC / MCU power supplies

• 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.
