Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTM4673IY is a quad output, dual 12A and dual 5A, switch-mode DC/DC step-down µModule (power module) regulator with an integrated 4-channel power system manager for sequencing, regulation (servoing), margin adjustment, monitoring, managing faults, providing telemetry and creating fault logs. input voltage range, with output voltages ranging from 0.6V to 3.3V for the 12A channel and 0.6V to 5.5V for the 5A channel. only large capacity input and output capacitors are required.

The LTM4673IY features a two-wire serial interface for precise output margining, trimming and programmable power-up and power-down timing control. An internal 16-bit ADC monitors input and all four output voltages, currents and temperatures. Faults can be programmed for over and under current, voltage and temperature threshold limits on all four output channels, as well as input over and undervoltage.

The LTM4673IY is supplied in a 16mm × 16mm × 4.72mm BGA package with a RoHS compliant terminal face.

• 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.
