TPS51285BRUKR Typical application Circuitry

TPS51285BRUKR

The TPS51285BRUKR is a dual-channel, synchronous step-down controller with differential remote sensing and integrated FETs, primarily designed for notebook system power supply solutions. TPS51285BRUKR It's commonly used in applications requiring efficient power conversion and distribution, such as notebook computers, ultrabooks, and portable electronics.

Applications and Usage Scenarios

1. Notebook Computers: The TPS51285BRUKR is ideal for managing power supply in notebook computers. It efficiently steps down the battery voltage to supply various subsystems and components.

2. Portable Electronics: For devices like tablets and other portable electronics, this chip provides stable power delivery, crucial for maintaining performance and battery life.

Key Parameters and Features

- Dual-Channel Operation: Offers two independent power rails for versatile power management.

- Integrated FETs: Reduces the need for external components, simplifying design and saving space.

- Differential Remote Sensing: Ensures accurate voltage regulation at the load, improving efficiency and performance.

- Adjustable Output Voltage: Allows for customization according to the needs of different applications.

Detailed Circuit Connection Example

Application Scenario: Power Management in a Notebook Computer

1. Power Input Connection (Pin VIN): Connect the battery's positive terminal to the VIN pin. This is the input voltage source for the TPS51285BRUKR chip.

2. Ground Connection (Pin GND): Connect the battery's negative terminal and system ground to the GND pin.

3. Output Voltage Regulation (Pins VOUT1, VOUT2): Connect these pins to the power rails of the notebook's main components (e.g., CPU, GPU). To adapt the output voltage to these components' needs, use external resistors.

4. Feedback Loop (Pins FB1, FB2): Connect feedback resistors from VOUT1 and VOUT2 to these pins to stabilize the output voltage.

5. Remote Sensing (Pins SENSE+ and SENSE-): Use these for differential sensing close to the load to ensure accurate voltage delivery, especially critical for sensitive components like the CPU.

6. Enable Pin (Pin EN): This pin is used to turn the chip on or off. Attach it to a switch or microcontroller so you can regulate the system's power supply.

Design Considerations

- Thermal Management: Given the integration of FETs, thermal management is crucial. Ensure adequate heat sinking and airflow.

- Load Requirements: Understand the power requirements of the components being powered, particularly the maximum current draw.

- PCB Layout: To reduce noise and guarantee steady operation, careful layout design is necessary.

- Protection Features: Incorporate additional circuitry for over-voltage, under-voltage, and over-current protection.

By keeping these factors in mind and utilizing the features of the TPS51285BRUKR, designers can effectively create efficient and reliable power solutions for notebook computers and other portable electronics.
