Part Number: LM5143 Other Parts Discussed in Thread: CSD18540Q5B , LM5137
Hi,
I am using the LM5143 in a DC/DC converter with an input voltage range 0-60V and an output of 24V. I have conducted a load test under the condition of 36V input and 24V/45A output…
Part Number: TPS62912 你好，
TPS6291x datasheet 8.2.2.2.3 Output Capacitor Selection 给出了输出电容值的范围：The effective output capacitance can range from 40 μF (minimum) up to 200 μF (maximum) for a single L-C system design. When using a second L-C filter, the first…
Part Number: BQ25756 Hi
We designed a supercapacitor pack charging board using the BQ25756 chip. The power input is 24V/4A. The capacitors used are 2.7V/30F, with 10 capacitors connected in series. The charging board outputs 27V and the charging current…
Part Number: TPS54560 tps54560.pdf 您好，我在立创商城看到的这款芯片，按照第24页推荐电路搭建好之后，不能正常输出5v。这个电路中我通过焊接R10或R11或R12来输出3.3v/5v/12v，但是都失败了，测FB脚电压也不是0.9v。然后我改变输入电压，输出电压也会跟着变化。
Part Number: SLUC222 Other Parts Discussed in Thread: UCC28950 , TINA-TI
I am simulating a PSFB converter using UCC28950 in TINA-TI. My input voltage range is 43V to 58V and output voltage is 240-385V ,output power is 4KW. I am seeing an issue with the simulation…
您好，请参考下面内容：
Yes, I have seen the MPPT get worse at low input voltage. Increasing the input capacitance helps. There is likely an optimum output R, input C and inductor L for a given duty cycle that would size the ripple ideally but I do not not have an…
