Hello, I want to design a wide-range input flyback converter with an input voltage of 120-1300VDC and an output of 24VDC using a dual-switch cascaded flyback circuit like PMP41009. Are there any other chips that can meet this requirement besides UCC28740…
Other Parts Discussed in Thread: LM51770 The LM51770 will be damaged. Both the input and output voltages are within a reasonable range, but VCC shorts with other pins. I also designed it by referring to the design manual. The ISNSP and ISNSN pins on my side…

The input supply of DCDC can range from 2.2V to 3.8V. DCDC regulates the output to 1.5V. But for GLDO, the
supply can range from 1.71V to 3.8V to generate a regulated output of 1.5V. DCDC hardware is designed so
that when the supply…
Part Number: OPA858 Dear Engineer,
I would like to ask a technical question regarding the OPA858DSGEVM board I purchased earlier.
At first, the board did not work when I applied a signal to the inverting input. After reviewing the schematic, I suspected…
I am sorry for not being clear before. Yes, I was talking about 'Voltage Output Swing from Rails'. There is no relationship between the zero-crossover input stage and output voltage swing from rails. However, the key difference between the OPA365/OPA4325…
Part Number: TIDA-010257 Hi team,
In the three-phase Vienna converter design of TIDA-010257, my AC input frequency range is from 75Hz to 270Hz. Can this range be covered by modifying the control and improving the PLL? Is it necessary to redesign the filter…

During Lab 1, the PFC (Power Factor Corrector) could normally boost the output voltage when the input DC voltage ranged from 0 to 20V. However, when the input voltage exceeded 20V, after the output voltage surpassed 50V, the output…
你好，能不能帮我向工程师转述以下问题，
Generally speaking, when designing a flyback switching power supply, it is usually designed according to the default input of AC85-265V. The technical documents about TI also design the flyback switching power supply according to this…

We are designing an IRIG-B AM demodulation circuit. The input signal is IRIG-B AM, the amplitude is peak-to-peak 0.5V to 12V, and the modulation ratio is 6:1 to 2:1. In order to extract the time information from the IRIG-B AM signal…
