Part Number: ISOW7844
Hello Support team,
The isolation circuit I designed is used to collect whether the keys are grounded. I have a 3.3V input and a 3.3V output, but when I measured the voltage at the output end, it was as high as 7V. I don't understand…
While debugging a mid-power push-pull isolated supply (~100W range), I’ve once again hit the classic wall:
Runs fine under light load MOSFET temps shoot up under full load EMI spikes appear around 180-250MHz during pre-compliance checks
The frustrating…
Part Number: OPA858DSGEVM Other Parts Discussed in Thread: OPA858
Dear Engineer, I wo uld like to consult you regarding an issue. I previously purchased an OPA858DSGEVM evaluation module. At first, when I applied a signal to the inverting input, the circuit…
您好
Functionally the schematic looks correct. I would recommend using an RCD clamp vs a TVS clamp. It helps dampen the ringing at the switch node which will improve EMI and power stage performance.
The output voltage is sense and controlled by VS pin…
Part Number: PMP41009 Other Parts Discussed in Thread: UCC28740 , , PMP41031
Hello, I am debugging a self-designed flyback switching power supply with an input of 90-900VAC and an output of 24VDC. I use the UCC28740 chip and adopt the relevant power supply…
Hello, the output power is 40W, and it does not need to comply with the AEC-Q100 standard. I want to build a high-voltage, wide-range input flyback switching power supply with a dual-switch cascaded structure like PMP41009. Do you have any good chip recommendations…
We are using the ACF2101 to detect the current from a photodiode (Hamamatsu S1336-8BQ). In our application, the light source flickers at 50 Hz. During each illumination period, we control the ACF2101 to integrate the output current of the photodiode with…
Part Number: LM3410-Q1 Other Parts Discussed in Thread: LM3410
Our company is currently utilizing your LM3410 IC in a T-BOX project, where it functions as a charging IC for a backup 0.1C NiMH battery with 600mAh capacity. The input power is a stable 5V…
Part Number: TPS56836 Input range 12V~24V
Output Fix 3.3V(Standby mode ) / Io max = 4.7A
使用在12V input時,電源插入時,TPS56836 power ic 冒煙燒毀,此時未開機.
是否Ti可作分析並說明燒毀的的原因及燒毀的Pin腳位置?
