Part Number: LMR33620 Hi team,
I have questions regarding a situation that Vin=0V and EN=3.3V
Does this device need power sequence control?
In current system, EN=3.3V and Vin=0V can be happened. What irregular will be happen in this case?
Regarding the…
Part Number: LMR33620 Other Parts Discussed in Thread: LMR33630 I had this issue on my prototype:
My LMR33620ARNX is switching at 140kHz with SW high 99.5% of the time. So Vout is close to Vin and FB is kept at 3V (when Vin=15V).
This was solved when I…
Part Number: LMR33620 Hello
It seem to me that I have the same problem.
In my prototype with LMR33620ADDA, connected as per the schematic below, Vout is always equal to Vin.
With Vin =24V I don't see any short circuit, but it is not working properly…
Part Number: LMR33620 Hello Good Day
I am using the buck converter LMR33620CQ5RNXTQ1 to convert 12V to 5V for my project,
however the output is always equal to the input.
I have followed the recommended design from the datasheet for the schematic and…
Part Number: LMR33620 Hi,
i would like to perform CE simulation on one our product. in the available Pspice model, i do not have idea about among the available which one needs to be used for my purpose. the Image is attached below. need a support.
Part Number: LMR33620 We would like to use the LMR33620 with a 28V supply and to get an output voltage of 26V. The device specifies a maximum output voltage of 24V, is this limit due to thermal considerations?
In cases where we need 26V the current will…
Part Number: LMR33620 My LMR33620ARNX is switching at 140kHz with SW high 99.5% of the time. So Vout is close to Vin and FB is kept at 3V (when Vin=15V).
Is the device broken or is there another explanation?
Part Number: LMR33620-Q1 Hi Team,
We see that there are two package options for LMR33620-Q1 in datasheet, RNX0012B and RNX0012C, but how to distinguish them in part number? We do not find it in datasheet.
Thanks.
Part Number: LMR33620 There are 2 formula (4) and (5) to calculate inductor, both calucated but the result of L is far difference.
which one is recommended? Lmin seems small at least, my understanding is correct?
Part Number: LMR33620 Other Parts Discussed in Thread: LMR33630 I am currently working on a power supply which have an input voltage around 24V. The device charges a supercapacitor which is then used as the power storage in case the 24V is absent. For…
