Part Number: DAC7612 We are facing an issue: how to quickly tell whether DAC7612U or DAC7612UB is mounted on our products. Our end customers have questioned how we can confirm that DAC7612UB, rather than DAC7612U, is used on the units. According to the…
Part Number: TLV9062 Hi TI Experts,
I'm using the TLV9062 to build a difference amplifier with a designed gain of 5.1 V/V.
Setup:
V+: 5V
V-: GND (Single Supply)
Topology: Standard 4-resistor difference amplifier.
Input Signal: 1kHz Sine wave…
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…
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…
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…
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: 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…
