Working Principle of LT1076HVCT7#PBF
The LT1076HVCT7#PBF is a switching DC-DC power supply which regulates the output voltage by controlling the ON and OFF time of the switching circuit at a constant frequency.When operating in the continuous Conduction Mode (CCM), the LT1076HVCT7#PBF comprises of two primary circuits. The input voltage from the power supply is fed to an inductor and a capacitor, which filters and transfers it to the output. The switching circuit contains an N-channel MOSFET and a start-up circuit. Once the power supply is enabled, the start-up circuit starts oscillating and turns on the MOSFET for a certain amount of time.During the ON period of the MOSFET, current flows from input to output via the inductor and thus charges the output capacitor. As the MOSFET switches OFF, the inductor is forced to discharge the current to the output and then back to the input, thus creating a flyback waveform.The LT1076HVCT7#PBF has a high switching frequency and thus acts as a current transformer to maintain a constant output voltage despite considerable changes in the load. It also supports voltage-mode control, allowing the user to regulate their load more accurately.Conclusion
The LT1076HVCT7#PBF is a high-performance synchronous step-down voltage regulator with a wide range of features and versatile applications. Its combination of high frequency operation, low quiescent current and excellent regulation makes it a suitable choice for many power supply designs.The specific data is subject to PDF, and the above content is for reference
