Part Number: LM2621 Other Parts Discussed in Thread: LMR62014 , TPS61175 , TPS61089 , TPS61378-Q1 Hi Team,
We would like to ask for your assistance to the customer's inquiries below.
We are looking at the LM2621 as an option for a booster converter.…
Hi Ranveer,
That's not easy to select a boost converter for your application because the source current is less than 20 miliamps. Typically the boost converter needs higher startup input current so that the output voltage can be regulated to desired voltage…
Part Number: LM2621 Other Parts Discussed in Thread: TPS61089 , TPS61372 Our customer is considering using the LM2621 under the following conditions.
Input: 2.7V-4.2V (lithium battery) Output: 6V-12V / 20mA-400mA
However, when simulating with WEBENCH at…
Hi Zack,
I apologize for the late reply. The input and output ground nets are connected. They were hidden by the picture cropping. Take a look at the layout below:
The output capacitor, C2 that I selected is the same low ESR and ESL Tantalum capacitor…
Part Number: LM2621 Hello,
In the data sheet for the LM2621 it states that PGND is pin 1 and SGND is pin 5.
However in the recommended PCB layout in the same datasheet shows pin 5 connected to the power ground and pin 1 connected to the ground of the…
Part Number: LM2621 Hi,
I am using the LM2621 device as a SEPIC converter, where I am generating a 5V voltage output from 4 to 7.5V input supply. I am not able to find any application note for the same.
Is there any document that explains the design calculations…
Part Number: LM2621 Hello ,
I am using LM2621 in a RF Transmitter. I generating 8.5V from 5.5V. During testing we have observed that, there is a 11Khz noise getting generated from LM2621. Which is getting modulated with RF. So I am seeing 11Khz Sours…
Part Number: LM2621 HI
My client is currently in circuit configuration with the LM2621. Circuit specifications are as follows. VIN: 3.7V to 4.2V (BAT) VOUT: 5V IOUT: 300mA The circuits are circuit based on the webench tool.
The problem is that in no-load…
Part Number: LM2621 Dear,
I am using LM2621 on our product - Application: step up from 3.7V to 11V (Vout) with typical application - reference circuit.
But in the absolute maximum ratings table: BOOT pins - maximum: 10V. In typical application: BOOT pin…
Part Number: LM2621 Other Parts Discussed in Thread: TPS61088
I want to convert the 3.7v- 5v input to 10 v output. I prepare a circuit but did not get 10v . Output voltage is 4.88v instead of 10v.
