Part Number: LM73606 Hello,
My customer would like to know the ripple voltage of LM73606EVM.
[Condition]
1) Input voltage 12V, Output voltage 3.3V output current 6A
2) Input voltage 5V, Output voltage 3.3V output current 6A
We would like to know input…
If anyone is facing an issue with this.
The following are the reasons for IC getting damaged.
1.) As the feedback pin is high impedance. If the divider circuit used is of the value above 400K. There are chances that during production testing or assembly…
Hi Alex,
Could you recommend a set-up based on this information?
Since you have on the board are 24, 12, 5, 3.3VDC power rails, I would recommend to create a negative -5V supply rail from switched-capacitor voltage inverter, such as LM2776 , LM27761 , LM26…
Part Number: LMR33630 Tool/software: WEBENCH® Design Tools So I designed a 5V supply using LMR33630ADDR, switching frequency is 400kHz. We expect the input voltage would be as high as 36V, since that is what the chip is rated. In testing, the chip would…
Frequenz = 100K for now. later will be 400k Sorry i can not Change to LSF because my prototype PCB the foodprint may not fit. If there would be some comment in the datasheet that it don´t work with I2C then i would have used diffrent part. Testing…
Melbin,
My only questions/concerns with your schematics are regarding the components connected to the EN pin.
The 100k resistor between EN and GND should not be required as there is an internal 400k pull down resistor present on this pin when the EN…
Hi Venkatavel,
Can you short the ADC inputs together to a mid-supply voltage and see if you are getting the datasheet noise performance at various filter, data rate and gain settings? This will tell you if there is an issue with the ADC or if the noise…
Part Number: BQ25703A Other Parts Discussed in Thread: BQ24610 , BQ24773 I have some question about BQ25703A;
1- I am using 1 cell 18650 Li-Ion battery( max 4.2V) and my input voltage is 5V-21V. So, I will use it in buck mode every time. Is it possible…
Part Number: LM73606 Hi team,
I'm an FAE supporting some industrial customers in Japan.
Please let me ask you about LM73606EVM.
Switching node of LM73606 was fluctuated when falling as shown in below.
Is this normal operation for this device?
Operating…
Hi Issii-san,
For example, if you use a DCDC converter for 5V power supply, if DCDC frequency = 400k Hz, then on the output voltage may have 400kHz, <30mV ripple depending on your output cap/inductor.
If the DCDC loop is not stable or due to other…
