Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The UCC27201ADRMR is a 3A, 120V half-bridge gate driver with 8V UVLO and negative voltage handling capability.The UCC2720xA series of high-frequency N-channel MOSFET drivers consists of a 120V bootstrap diode and high-side/low-side drivers with independent inputs for greater control flexibility. This enables N-channel MOSFET control in half-bridge converters, full-bridge converters, dual-switch forward converters, and active clamp forward converters. The low-side and high-side gate drivers are independently controlled and matched with a 1ns delay between turn-on and turn-off of each other. The UCC2720xA has an enhanced ESD input structure and its HS pin is capable of withstanding voltages of up to -18V, which results in improved performance in noisy power environments.

• 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?
