Part Number: LMR16030PEVM Other Parts Discussed in Thread: LMR16030 Hello, I have encountered some technical problems when using the LMR16030 chip. Could you help me solve them? Design requirements: need to design DC-DC circuit. The input is 18V to 60V…
Part Number: OPA838
Here's my schematic why I can't output a properly amplified signal when the input signal amplitude is 1.5V.
When I input a signal amplitude of 1.2V it is ok. And according to the info in the manual a 1.5V signal is not outside…
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…
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…
Hi,
They are similar specs, which is why the numbers are so close, but we measure them differently.
SNR is measured by grounding the ADC inputs to 0. The resulting digital output from the ADC will be the effective noise floor of the ADC. SNR by definition…
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…
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…
