Other Parts Discussed in Thread: LMR61428 Hi all Would you mind if we ask LMR61428? Our customer's condioton is as follows; -Vin=3.5V -Vout=4.2V -Iout=1.2A Our customer would like to calculate Maximum Fsw. However we could not find Minimum on time or…
Other Parts Discussed in Thread: LMR61428 , BQ24195 Hi,
We have connected the output of LMR61428 (5V) to BQ24195 input via pfet.
The microcontroller senses the solar voltage continuously and upon good solar voltage, it enables the PFET so that the…
Other Parts Discussed in Thread: LMR61428 , LM3481 Hi,
I would like to constitute a SEPIC circuit from LMR61428.
Now, the constant was examined by power designer, as shown in a lower figure.
In this case, between which terminals is C1 arranged…
Other Parts Discussed in Thread: LMR61428 , LMR61428XMMEVM Sir I purchased LMR61428 IC and LMR61428 Evaluation Module LMR61428XMMEVM , When I assembled the LMR61428 IC Circuit on PCB I am getting Vout ==3.3 times of Vinput.
But in Evaluation module…
Hi Britt,
Let me elaborate a little .
We are using LMR61428 in our project from 3.7V to 5 V and 5V to 12 v generation.
As assembled card comes to us this is not working and giving only 1.24V output.
I just want to simulate it to TINA so I downloaded…
Other Parts Discussed in Thread: LMR61428 , LM2621 , LM3481 Hi,
I'm looking for an application note, describing the SEPIC configuration of the LMR61428. As mentioned in the datasheet the LMR61428 could be configured as a SEPIC converter. I will need…
Other Parts Discussed in Thread: LMR61428 , LM3481 Hello, I am trying to design a DCDC module which employs LMR61428. As I reading the datasheet:
" However if the VOUT is outside this range, the VDD pin should be connected to a voltage source whose…
Other Parts Discussed in Thread: LMR61428 , TPS61090 , TPS63020 HI,
I need a boost to take a 2.8-3.2Vin and generate a 3.8v out need 1.6A max and 150mA min. Quiescent current is very important so I was looking at the LMR61428 but I d on't see a datasheet…
Other Parts Discussed in Thread: LMR61428 hi
i am using LMR61428 ic for 5V to 12V / 100mA conversion.
Below symbols are as per datasheet of IC.
According to datasheet i have designed Rf1, Rf2.
My question are
1) How to design R1, Rfq, C3 values…
Part Number: LM2623 Other Parts Discussed in Thread: LMR61428 Hello I want too use LMR61428 as an alternate for LM2623. I have found out that the only difference between these parts is the junction to ambient temperature for LM2623 is is 152.5C/W & for…
