Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPSM82901SISR Synchronous Buck Converter Power Module is a very efficient, small and flexible synchronous buck DC-DC converter in a MicroSiP package. The easy-to-use TPSM82901 offers selectable switching frequencies of 2.5MHz or 1.0MHz, allowing the use of small components and providing fast transient response. With a DCS control topology, the TI TPSM82901SISR power modules support high output voltage (VOUT) accuracy of ±1%. A wide input voltage range of 3V to 17V supports a variety of nominal inputs such as 12V supply rails, single or multi-cell Li-Ion, and 5V or 3.3V supply rails.

The TPSM82901SISR is available in a small 11-pin MicroSiP package measuring 3.0mm x 2.8mm x 1.6mm with an integrated 1μH inductor.

Test and Measurement

• 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.
