Description

The XDPL8105 is a digital flyback controller that integrates both the control and protection functions needed for flyback converter designs. It uses a digital signal processing (DSP) architecture, allowing it to achieve high accuracy and reliability while also optimizing efficiency. The IC is particularly suited for power supplies requiring low standby power, high efficiency, and a compact design.

Features

  • Digital Control: The XDPL8105 uses a digital controller for more precise control of the flyback converter. It offers accurate voltage regulation and enables dynamic response adjustments.
  • Wide Input Voltage Range: Typically supports a wide input range of 90V to 265V AC, making it suitable for universal power supplies.
  • High Efficiency: Designed for high efficiency with the help of digital feedback and advanced power management, ensuring minimal power losses.
  • Integrated Power Management: The IC integrates several power management functions such as primary-side regulation, leading to a simplified external circuit design and reduced component count.
  • Constant Output Voltage: Ensures constant output voltage regulation using feedback from the primary side, eliminating the need for an optocoupler in many designs.
  • Internal Error Amplifier: Includes an internal error amplifier for accurate voltage regulation.
  • Over-Current Protection (OCP): Built-in over-current protection ensures the power supply remains safe during fault conditions.
  • Over-Voltage Protection (OVP): Includes over-voltage protection, preventing excessive voltage at the output.
  • Thermal Shutdown: Protects the IC and external components by shutting down in case of overheating conditions.
  • Soft-Start Function: Incorporates a soft-start mechanism to prevent excessive inrush current at power-up, reducing stress on components.
  • Low Standby Power: The IC is designed to minimize standby power consumption, making it ideal for energy-efficient designs.
  • Flexible Feedback and Control: It allows flexibility in feedback and control to optimize for different loads and operational conditions.

Specifications

  • Input Voltage Range: Typically 90V to 265V AC (universal mains input).
  • Output Voltage Regulation: Provides precise constant output voltage regulation.
  • Switching Frequency: Fixed or adjustable switching frequency depending on the application, usually around 65kHz to 100kHz.
  • Operating Temperature Range: Typically -40°C to +125°C, allowing the IC to be used in a wide range of environmental conditions.
  • Package Type: Available in SMD (Surface-Mount Device) packages, such as SOIC-8 or other compact configurations suitable for high-density PCB designs.
  • Maximum Output Power: The IC can drive power outputs typically up to 20W to 50W, depending on the specific design.
  • Output Voltage Tolerance: Typically offers tight regulation within ±5% of the desired output voltage.
  • Current Sensing: Uses primary-side current sensing for accurate regulation without needing an optocoupler.
  • PWM Control: Implements pulse-width modulation (PWM) for controlling the switching of the flyback converter.
