SRK2001TR Typical application Circuitry

SRK2001TR

SRK2001TR is a synchronous rectification controller designed primarily for switch mode power supplies (SMPS) with high efficiency. It's particularly effective in low voltage, high current environments. This controller is commonly used in applications like server power supplies, telecommunication equipment, and high-performance power converters.

Application Scenario: Server Power Supply

In this application, SRK2001TR is employed to enhance the efficiency of a server's power supply unit (PSU), ensuring stable and reliable power delivery to the server components while minimizing heat generation and energy loss.

Circuit Connection Details

1. Input Voltage Connection

- Highlight: SRK2001TR operates by receiving its input from the power supply transformer. The Vcc pin (Pin 8) is connected to a stable voltage source.

- Point of Focus: The voltage level must be within the specified range for SRK2001TR to ensure proper operation without causing damage to the IC.

2. Grounding Scheme

- Highlight: The ground (GND, Pin 5) of SRK2001TR is essential for its operation and should be connected to the system ground.

- Point of Focus: A robust and low-resistance grounding path is crucial to prevent noise and ensure the stability of the SRK2001TR.

3. Drive Output Connection

- Highlight: The GATE pin (Pin 6) of SRK2001TR connects to the gate of the external MOSFET, controlling its on and off states.

- Point of Focus: The drive strength and the gate charge of the external MOSFET must be compatible with the output capacity of the SRK2001TR to ensure efficient switching.

4. Feedback and Sensing

- Highlight: The VS pin (Pin 1) senses the voltage across the external MOSFET. This feedback is crucial for the SRK2001TR to determine the correct timing for turning the MOSFET on and off.

- Point of Focus: Accurate sensing is vital. Any voltage drop in the path (due to PCB traces or bad connections) can lead to incorrect timing, reducing efficiency or damaging components.

5. Compensation Network

- Highlight: The COMP pin (Pin 2) is used to connect a compensation network, typically involving resistors and capacitors.

- Point of Focus: The values and stability of these components are crucial in defining the dynamic response of the SRK2001TR, affecting the overall stability and performance of the power supply.

Design Considerations

When designing a circuit with SRK2001TR, several key factors should be meticulously addressed:

1. Thermal Management: Ensure proper heat dissipation for SRK2001TR, as power conversion processes might generate significant heat.

2. PCB Layout: Carefully plan the PCB layout to minimize the loop area for the high-current paths and to separate the control paths from the power paths to reduce noise and interference.

3. Component Selection: Choose the external components, especially the MOSFET and compensation network components, to match the drive capability and stability requirements of the SRK2001TR.

4. Protective Measures: Implement adequate protection mechanisms, such as over-voltage, over-current, and over-temperature protections, to safeguard the SRK2001TR and the overall system.

5. Compliance and Testing: Ensure the design meets all the regulatory standards for your application and conduct thorough testing to validate the performance and reliability of the SRK2001TR in the intended application.

By thoroughly understanding the operational characteristics and parameters of SRK2001TR and considering these design aspects, engineers can effectively integrate this synchronous rectification controller into high-efficiency power supply units, optimizing performance and reliability in demanding applications like server PSUs.
