The CA21116012 is a 12-bit, 0.20A current-mode asynchronous buck switching regulator controller. It was specifically designed for off-line and DC-to-DC converter applications, making it easy to design in a variety of applications such as notebooks, PCs, cell phone chargers, TV\'s, etc. The CA21116012 is an advanced, high frequency, current mode controller with a two stage control path. The control loop uses a voltage mode control in the first stage and a current mode control in the second stage, the output voltage being sensed at the FB pin. This dynamic behavior makes the CA21116012 a superior choice for Advanced Voltage Positioning (AVP) inside a system power supply where output voltage sensing is remote from the switching regulator. The CA21116012 also offers excellent regulation, fast turn-on and turn-off times, and a wide operating range.The CA21116012 is optimized as a low cost current regulator and is ideal for new designs requiring remote sensing, excellent dynamic response, high efficiency and EMI performance.

Applications

CA21116012 is designed for *off-line* and DC-to-DC converter applications, making it easy to design in a variety of applications such as notebooks, PCs, cell phone chargers, TV\'s, etc.It is also suitable for other applications where high efficiency, high performance and low EMI are desired. Examples include applications such as medical equipment, industrial power supplies, automotive electronics, and motor drivers.

Working Principle

The CA21116012 is a two-stage current regulator using voltage mode, current mode control. In the first stage, the CA21116012 uses a voltage-mode control loop that takes input voltage and the output voltage as an input. This voltage-mode control compensates for the error between the input and output.In the second stage, the CA21116012 uses a current mode control loop that senses the current in the output and compares it with a reference voltage. This current mode control sets the output voltage according to the sensed current. The CA21116012 also has built-in protections to ensure proper operation and is optimized for low-cost current regulation.

Performance Features & Benefits

The CA21116012 provides a wide operating range and excellent performance. The device is well suited for applications requiring high-efficiency, high-performance and low EMI. The main benefits of the CA21116012 are:
  • Optimized for high-frequency operations, allowing for higher-efficiency designs
  • Fast turn-on and turn-off times
  • Highly dynamic response with smooth loop-compensation
  • Lower power consumption with maximum duty cycle control
  • Integrated safety features for better system protection

Conclusion

The CA21116012 is a great choice for applications requiring high performance and low EMI. The advanced two-stage control, wide operating range, fast turn-on and turn-off times, and integrated safety features make it an ideal choice for a variety of applications.
