Part Number: CSD17307Q5A HI,
The drain of CSD17307Q5A output is upward overshoot when the MOSFET from trun on to trun off,then it will fall slowly.I wonder to know what caused it,can anybody tell me?
In figure 1 the yellow waveform is the output of…
Part Number: CSD17307Q5A Other Parts Discussed in Thread: CSD17577Q5A , CSD17581Q5A Customer is looking for replacement for the IRFH8324TRP and IRFH8318TRP. Do you have any suggestion? Thank you.
Part Number: BQ24735 Other Parts Discussed in Thread: CSD17307Q5A We have implemented the design pretty much verbatim as per the BQ24735EVM-710 evaluation PCB schematic, including using the same peripheral components (see below schematic).
We have seen…
Hi Hari,
Thanks for capturing the waveforms. Since the input FET portion of your schematic matches the BQ24725A EVM, I'm not sure why using the same CSD17307Q5A FET results in ACFET damage on your board.
However, I don’t see any concerns with changing…
Part Number: CSD19536KTT Other Parts Discussed in Thread: CSD17307Q5A , CSD17304Q3 Hi everyone,
Would you please suggest some mosfet part numbers for my application please ?
Voltage: 24V
Current: 10 Ampers
Trigger will be 3.3V, PWM.
Thanks!
Hi Suy,
Thanks for the inquiry. I will try to run the simulations myself to determine why you're seeing this behavior. I assume this is also related to your other post on the CSD17307Q5A. I will send you a follow up response as soon as I have more information…
Hello Tomoya Ide

Part Number: LM3481 Other Parts Discussed in Thread: CSD17307Q5A Hi,
I develop the boost converter using LM3481. Hardware specs are Vin= 3-8V, Vout = 9 V, Iout=1 A.
But i have a problem. Minimum input voltage is 3.5-3.6V. Hardware is not working with…
