Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS61040QDBVRQ1 device is a high-frequency boost converter for automotive applications with output voltages up to 28 V output voltage. NiMH/NiCd batteries or a single lithium-ion battery produce output voltages up to 28 V and support input voltages from 1.8 V to 6 V. The TPS61040QDBVRQ1 device operates with a switching frequency of up to 1 MHz, enabling input voltages up to 1.8 V to 6 V. The TPS61040QDBVRQ1 device is a high-frequency boost converter for automotive applications. The switching frequency of up to 1 MHz allows the use of small external components such as ceramic elements and tantalum output capacitors. Combined with the space-saving 5-pin SOT-23 package, the TPS61040QDBVRQ1 devices achieve a small overall solution size. the TPS61040QDBVRQ1 devices have an internal 400 mA switching current limit, while the TPS61040-Q1 devices have an internal 400 mA switching current limit and the TPS61040QDBVRQ1 devices have 250-mA switching-current limiting, providing lower output voltage ripple and allowing the use of smaller form factor inductors.The TPS61040QDBVRQ1 devices operate in a pulse-frequency modulation (PFM) scheme with constant-peak current control. The combination of low quiescent current (28 µA typical) and an optimised control scheme allows the device to operate at high efficiency over the entire load range.

• 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.
