Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS62740DSSR is the industry's first buck converter to feature a typical quiescent current of 360nA and to operate with a miniature 2.2µH inductor and 10µF output capacitor. This new DCS-Control™ based device extends the light load efficiency range to below 10µA load current. The TPS62740 supports output currents of up to 300mA and operates from rechargeable Li-ion batteries, Li-ion chemistries such as Li-SOC12, Li-MnO2 and two or three alkaline batteries. With an input voltage range of up to 5.5V, operation from 1 USB port and a thin film solar module is also possible. The output voltage is user selectable from 1.8V to 3.3V (100mV steps) using the 4 VSEL pins. The TPS62740 features low output ripple voltage and low noise with the use of small output capacitors. Once the battery voltage approaches the output voltage (close to 100% duty cycle), the device enters ripple-free 100% mode operation to prevent an increase in output ripple voltage. The device then stops switching and the output is connected to the input voltage. The TPS62740 is available in a small 12-pin 2mm x 3mm2 WSON package and supports an overall solution size of 31mm2.

• 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.
