Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS54622RHLT device, in a thermally enhanced 3.5mm × 3.5mm VQFN package, is a full-featured 17V 6A synchronous step-down converter; with high efficiency and integrated high-side and low-side MOSFETs, the device is optimised for small footprint designs. Current-mode control significantly reduces component count, while inductor size is reduced by selecting a high switching frequency, resulting in further space savings.

The output voltage start-up ramp is controlled by the SS/TR pin, which supports both independent power supply operation and tracking mode. Additionally, power sequencing can be achieved by properly configuring the enable and open-drain power good pins.

Cycle-by-cycle current limiting of the high-side FET protects the device in overload situations and is enhanced by low-side pull current limiting to prevent runaway current. In addition, a low-side sink current limit is provided to turn off the low-side MOSFET to prevent excessive reverse current. Intermittent protection is triggered when the overcurrent duration exceeds a preset time. Thermal intermittent protection disables the device when the die temperature exceeds the thermal shutdown temperature and re-enables the part after the built-in thermal shutdown intermittent time.

• 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.
