Part Number: LM2622 Dear TI :
We have one design using LM2622. The power level is boosted to 8V from 3.8V using battery.
1. Use 1.25 MHz applications, L = 4.7uF_1.9A
2. RFB1 = 75KOhm, RFB2 = 10KOhm
3. Rc = 56KOhm, Cc =2.2nF
Please provide your…

Hi,
I am using LM2623 and LM2622 chips for step-ups in my design.
I designed it so I will use only one of them at a time.
I have checked both of them, and I have…

Same content as the previous question, The post is locked and asks again.
Attach the schematic file. It is to increase the audio amplifier range. …
Part Number: LM2622 Other Parts Discussed in Thread: TLV61048 I want to simulate LM2622 on PSPICE for TI, but macro model was not found.
Is there way to get LM2622 macro?
Best regards,

Hi Jeon,
Are you sure you want to use LM2622? LM2622 is a step up boost converter with MOSFET integrated. Vin pin should be connected to input at least.
Could you share the WEBENCH design file?
Hi Giovanni,
The LM2622 is a non-isolated controller and the post belongs in another forum. I will move it for you and one of my colleagues will pick it up there.

Other Parts Discussed in Thread: TPS61220 , TPS61260 , LM2622 So in my application I have a power source that is ideally at 3.6V but can drop as low as 2.6V while the circuity it powers needs a well regulated 3.6V. The load, however, is a pretty light…
Other Parts Discussed in Thread: LM2622 , TPS61372 Team,
I need to boost 5.0 (or 3.3) to 6.6V. The output current requirement is .2A max, but the parts I’m considering are in the .35 to .5A range. Size and efficiency are the primary constraints. The…
