Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS53015DGSR device is a single-channel, adaptive on-time D-CAP2 ™ mode synchronous step-down controller. This device enables system designers to perfect the kit that includes power bus regulators for various terminal devices with an economical, efficient, low number of external components and low standby current solution. Its technical features are as follows:

D-CAP2™ mode control

Fast transient response

Loop compensation can be achieved without external components

Compatible with ceramic output capacitors

High initial reference accuracy (±1%)

Wide input voltage range: 4.5V to 28V

Output voltage: 0.77V to 7V

Low-side RDS(on) non-destructive current detection

Fixed soft start time: 1.4ms

Non-current pre-bias soft start

Switching frequency: 500kHz

Period-by-cycle overcurrent limiting control

The auto-jump Eco-Mode™ ensures high efficiency under light load

Output in a normal power supply state

OCL/OVP/UVP/UVLO/TSD protection

Adaptive gate driver with integrated boost PMOS switch

Thermal compensation OCP, 4000ppm/°C

10-pin VSSOP

The main control loop of TPS53015DGSR adopts D-CAP2 mode control, achieving extremely fast transient response without the need for external compensation components. The adaptive on-time control function supports seamless conversion between the PWM mode under higher load conditions and the Eco-mode™ operation mode under light load conditions. The Eco-mode operation mode enables the device to maintain high efficiency under relatively light load conditions.

This device can also adapt to low equivalent series resistance (ESR) output capacitors (such as POSCAP or SP-CAP) and ultra-low ESR ceramic capacitors. The TPS53015DGSR features an input voltage ranging from 4.5V to 28V and an output voltage from 0.77V to 7V, enabling convenient and efficient operation.

• 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.
