Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The NCP1200, housed in a SO-8 or DIP-8 package, is a major leap forward in the implementation of ultra-compact switch-mode power supplies. Thanks to a new concept, the circuit can implement a complete off-line battery charger or standby SMPS with very few external components. in addition, the integrated output short-circuit protection allows designers to build very low-cost AC/DC wall-mount adapters in connection with simple feedback schemes. With an internal architecture operating at a fixed 40 kHz, 60 kHz or 100 kHz frequency, the controller can drive low-gate charge switching devices such as IGBTs or MOSFETs, thus requiring very low operating power consumption. Thanks to current mode control, the NCP1200 greatly simplifies the design of reliable and inexpensive off-line converters with excellent audio sensitivity and intrinsic per-pulse control. For example, when the output power demand disappears and the current setpoint drops below a specific value, the IC enters a so-called skip-cycle mode, providing excellent energy efficiency at light loads. Because this occurs at low peak currents, no noise is emitted. Finally, the IC is self-powered to the DC rail, eliminating the need for an auxiliary winding. This feature ensures operation in the presence of low output voltages or short circuits.

• 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.
