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…
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…
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…
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…
Hi Jeff,
LM3224 cannot output 5.5V, 1.3A because it will trigger current limit.
For lm2557, inductor current ripple could be selected betweeen 20~40%. Have you tried setting R1 7.8kohm, R2 2kohm to get a 6V output voltage like below picture. Then…
Other Parts Discussed in Thread: LM3224 I use the LM3224 to provide +-8V to a headphone amplifier circuit. In my circuit I see ringing around 108MHz. I suspect PCB trace stray inductance. In your experience, what is the best way to reduce unwanted ringing…
