Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The UCC28056CDBVR is a PFC controller. The controller can directly drive up to 300W of output power while ensuring low sinusoidal line input current distortion and near 1 power factor. The device includes burst mode operation to further improve light load performance, allowing systems to comply with challenging energy efficiency standards without having to turn off the PFC. The UCC28056CDBVR can drive PFC power stages up to 300W, ensuring low sinusoidal line input current distortion and near 1 power factor while keeping the PFC ‘always on’. always on’. When used with the LLC controller UCC28056CDBVR, the 6-pin device eliminates the need for an auxiliary flyback converter, which is often required in systems to achieve good standby performance, while achieving a power consumption of less than 80mW at 230Vac. The device also enables instant-on while minimising the number of 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.
