Working Principle of LMZ12002TZX-ADJ/NOPB

The LMZ12002TZX-ADJ/NOPB is based on a feedback principle that compares the output voltage with the reference voltage and adjusts the power delivered accordingly in order to maintain the desired output voltage. This device uses a synchronous switching converter, also known as an active clamped waveform converter, to accomplish this task. The synchronous converter consists of the voltage regulator, the transformer, the transformer primary side switches which are typically implemented with metal oxide semiconductor field effect transistors (MOSFETs), the transformer secondary diode, and the output capacitor. The voltage regulator is implemented using an operational amplifier (Opamp) and compares the feedback voltage from the secondary side to the reference voltage. The power delivery of the synchronous converter is controlled by the primary side switches. The switches are driven by a signal generated from the voltage regulator with an internal ramp generator. When the switch is closed, a dot voltage is induced across it. This dot voltage, when the dot current is limited to a certain level, is used to maintain the peak voltage across the switch at a fixed level, ensuring a near ideal operating efficiency.

Conclusion

In conclusion, the LMZ12002TZX-ADJ/NOPB is designed to meet a wide range of portability, power and accuracy requirements. It is widely used in various fields, such as industrial, automotive, telecommunication, battery charging, and medical, and provides a 4:1 wide input voltage range, 3A peak load current, and ENEC compliance. The LMZ12002TZX-ADJ/NOPB is also capable of asynchronous rectification, making it a great choice for any project needing increased power. Its working principle is based on an active clamped waveform converter which regulates the power delivery using the voltage regulator and maintains the desired output voltage.
