Working Principle

The ACT4529YH-T1011EW utilizes full-wave controlled rectifier topology with current-mode switching control to achieve a highly efficient power conversion. It uses two switches, a high-side switch and a low-side switch, to regulate the output voltage. When the voltage on the low-side switch is lower than the reference voltage, the output voltage is regulated. The control IC regulates the pulse width of the switches by detecting the current flow through the switches. When the current exceeds the predetermined level, the control IC reduces the pulse width to protect the system. Furthermore, the ACT4529YH-T1011EW includes various protection features such as over-voltage protection, over-temperature protection, and short-circuit protection to ensure the safety and performance of the system.

Conclusion

The ACT4529YH-T1011EW is a DC DC switching regulator module from Analog Devices, Inc. It utilizes full-wave controlled rectifier topology with current-mode switching control to achieve high-efficiency power conversion and adjustable output voltage range. The ACT4529YH-T1011EW is suitable for use in a variety of applications such as portable electronic devices and embedded systems. In addition, the ACT4529YH-T1011EW has various protection features for safe and reliable operation.
