Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX20499CAFOC/VY+ is a high-efficiency synchronous buck converter with an input voltage range of 3.0 V to 5.5 V and an output voltage range of 0.5 V to 1.275 V. This device has a wide input/output voltage range and is capable of delivering peak output currents of up to 16 A, making it well suited for on-board point-of-load and post regulation applications. the MAX20499C has an output error of ±1 5% over the load , line, and temperature ranges with an output error of ±1.5 percent.

The MAX20499CAFOC/VY+ features a 2.2MHz fixed-frequency PWM mode, which provides improved immunity and load transient response. 2.2MHz operation supports the use of full ceramic capacitors and reduces external component count. Spread Spectrum Modulation option fully reduces electromagnetic emissions. An integrated low RDS(ON) switch improves efficiency at heavy loads and simplifies the layout to make it simpler than discrete solutions.

The MAX20499CAFOC/VY+ uses a factory preset output voltage. The I2C interface supports dynamic adjustment of the voltage according to the programmed slew rate. Other features include programmable soft-start, over-current protection, and over-temperature protection.

• 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.
