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…
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…
1 & 2) The differences can be attributed to transistor type and not design/architecture. The transistors in AVC cannot be found in LVC because both support different voltage ranges. AVC uses transistors that work best when using voltages in the 1.8V…
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: TPSM33615
Currently, we need to design a power conversion circuit with an input of 28V and an output of 12V. However, when using the calculator for design calculations, the absence of a model option corresponding to the 12V output has led…
Part Number: TIDM-02013
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…
Part Number: LM5155 HI,
I'm using the LM5155 to design a circuit with a 5V input and a 12V 3A output. However, I have no idea how to design the transformer. Here is my schematic diagram. Could you provide the winding number so that I can also apply for…
Part Number: PCA9306
Refer to the figure above.
there are My design circuit / recommends circuit of datasheet / waveform testing (test points: PCA9306 PIN3/PIN6/PIN8; net: IIC_EN).
The IIC_EN signal is pulled high 5 ms ahead of I²C communication. PIN6…
Part Number: LM3405A
When using LM3405A, my input voltage is "3.8V - 4.2V", and the If and Vf of the loaded LEDs are: 100mA 1.61V, 200mA 1.88V, 300mA 2.14V, 400mA 2.40V. I want to parallel two LEDs, and R1 uses 0.2 ohm to make the output current 1Amax…
Part Number: LM5007
Currently, the LM5007 is designed with an
input of 48V and an output of 12V. It can work
normally when powered on to48V instantly,
but the power supply does not work
abnormally when it reaches48V instantly.
The output is 2.2V. What…
