Part Number: LM3224 Other Parts Discussed in Thread: TPS61089 As per the data sheet we design schematic for 12V/1A output, but during the testing time this board fail to delivered the power 12W at the output with 12w load. when we connected the load of…
Part Number: LM3224 Hi,
Good Day. Need below mentioned electrical characteristics of IC LM3224MM-ADJ/NOPB. Please advise. Thank you very much.
Thermal shutdown hysteresis High level input voltage Low level input voltage Input leakage current Load regulatio…
Part Number: LM3224 Dear expert,
I am looking for P2P with MP1542.
I find LM3224 maybe a right solution for me, but have little concern about device package.
Is MSOP8 P2P with our 8 lead VSSOP?
If it's confidential, please contact with me offline. (benkuo…
Other Parts Discussed in Thread: TPS55340 , LM3224 Looking for low cost step up from 2.7V to 20V/50MA
I found TPS55340 and LM3224
Any other recommendation?
Other Parts Discussed in Thread: LM3224 I'm bringing up a prototype where an LM3224 delivers 8mV in a 5V->8V configuration. When I scope the SW pin it looks like a square-ish pattern intersected with a sine-ish pattern. The stated 24MHz SRF of the inductor…
Other Parts Discussed in Thread: LM3224 , LM2936 , LMH6643 , LM4871 , LM4923 , LM2622 Hello,
I’m looking for the thermal resistance from junction to ambient (θja) of the LM3224. In the datasheet, it talks about using θja to calculate power, but it’s not called…
Hi Jay,
The input current is calculated as (12V*2A)/(4V*0.9)=6.7A when assuming efficiency is 0.9. The switch current limit needs to be more than 7A at least. So LM3224 doesn't satisfy your requirement.
For your application, TPS61288 is recommended…
Hi,
I'm using the LM3224MM-ADJ to convert a 3.7 V input to a +/- 10V output (using the design example in the data sheet to get the negative output voltage). With output currents of 60-80 mA I get a terrible efficiency of only 30%, and I think the layout…
Hi Zack,
The 12VDC load we are powering using LM3224 has an on board 3.3V LDO with supercaps on output. We are having pulse requirements of 1Amp on this 3.3VDC which is being taken care of by the super caps. So LM3224 outputs remains at 12VDC/100 mA. …
Part Number: LM2577 Other Parts Discussed in Thread: LM3224 Tool/software: WEBENCH® Design Tools I was wondering if the LM2577 adj would work configured with the load connected to the sense pin. the 2 pots will give me the needed current to ground My…
