Part Number: LM2621 Tool/software: Hi all,
I have built a PBC where the LM2621 is used as step up converter according to Chapter 8.2.1 / Fig 13 of the data sheet.
The circuit works fine down to an input voltage of 2.2 V, then when it comes lower,…
Part Number: LM2621 Other Parts Discussed in Thread: TPS61175 , LM5157-Q1 , LM5157 Tool/software: Hi Team, Customer is asking for a low cost device which is similar with LM2621, used in Sepic topology. Could you please help provide a suitable device here…
Part Number: LM2621 Tool/software: We are using the LM2621 to boost a "9V" battery to 12V to power an MCU and a electro-mechanical lock. The MCU controls a high side switch to power the electro-mechanical lock. A flyback diode protects the high side switch…
Part Number: LM2621 Tool/software: Hi Guys,
Set up the sample circuit breadboard style from the datasheet (Figure 13). All components used were following the schematic aside from RF1 and RF2 (100K and 22.2K).
Input Voltage: 5V
Output Voltage: ~7V…

Part Number: LM2621
Hi everyone!
I have built a device using LM2621 step-up converter. Please find atached schematic for reference. The output voltage of LM2621 is conneted to the TDA2005 audio amplifier.
The problem is that an output voltage ripple…
Hello,
Thank you for your answer.
Yes, I have less current around 0 to 15-20 milliamp as Source. Could you suggest any other better Voltage boost Ic Which able to work and boost in low current also ( 0-2vdc voltage with 15 mAmp low current ) to…
Part Number: LM2621 To whom it may concern, I am using the LM2621 as a 5V boost converter to power another ldo regulator to 3.3V.I am having an issue with CF1 or known as the feed forward capacitor. When I do not use a feedforward capacitor I am receiving…
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…
