Working Principle

The PT4226C is a high-frequency switching power supply that works by converting the DC input voltage to a desirable output voltage. It is a non-isolated buck-boost converter that operates in a buck or boost mode depending on the input and output voltage. In buck mode, the input voltage is regulated and boosted to the desired output voltage. In boost mode, the output voltage is increased from the input voltage without compromising the quality of the input voltage.The converter operates with a peak current mode control. It uses high-speed high-efficiency switching transistors to reliably switch the power from the input to output. The on-time and off-time of the switching is determined by a cycle-by-cycle peak current, ensuring stability and an excellent conversion efficiency.

Conclusion

The PT4226C is a versatile DC-DC converter that is suitable for use in many applications. It can be used to power mobile devices, automotive systems, and other consumer electronics. It works by converting the DC input voltage to a desired output voltage, using a high-frequency switching power supply with high-speed switching transistors. It operates with a peak current mode control, which ensures stability and excellent conversion efficiency.
