Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The STPMIC1DPQR power management IC is a wide fully integrated PMIC designed for use in highly integrated application processor based designs where low power consumption and high efficiency are required.The STPMIC1 PMIC integrates advanced low power features and is controlled by the host processor via I2C and IO interfaces. The PMCI integrates four synchronous buck converters which are optimised for ultra-high efficiency. The device also contains low dropout voltage (LDO) regulators to power the application processor as well as system peripherals such as DDR memory, flash memory and other system devices.

The STPMIC1DPQR's boost converter can drive up to three USB ports (two 500mA host USB and one 100mA USB OTG.) The STPMIC1's advanced bypass architecture smoothly regulates the VBUS of the USB ports on batteries as well as consumer 5V AC-DC adapters.

The STPMIC1DPQR power management IC is available in a WFQFN-44L package and has an ambient operating temperature range of -40°C to +105°C.

• 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?
