Part Number: LM22671 Looking at your LM22671 to create 18-28V IN, 15.5V OUT, 250mA. I have a question about minimum load current, my load could be as small as 4mA and as high as 205mA, what minimum load must be maintained on this buck regulator? Will…
Part Number: LM22671 Other Parts Discussed in Thread: LM2674 Hi team, My customer plan to change from LM2674 to LM22671. But they do not need Soft Start and RT. Is it okay to open SSpin and RTpin? Sincerely. Kengo.
Part Number: LM22671 Hi Guys
Our customer want to use Buck convert as a current source. Input 7-15V; Output: 100mA current source; Vout is about 3.6V. They use it to charge a three series batteries(Ni-MH). Their battery vendors don't suggest that they…
Other Parts Discussed in Thread: LM22671 , LM22674 Hi all Would you mind if we ask LM22674 and LM22671? The switching frequency of LM22671 and LM22674 are MAX600kHz, MIN400kHz. Do you have distribution of switching frequency? Because, our customer would like to…
Other Parts Discussed in Thread: LM22671 Hi all
Would you mind if we ask LM22671?
<Condition>
Vin=24V
Vout=-12V
Iout=-0.1A
Fsw=830kHz
How much is the inductor fitable?
On calcuating, L is 330uH.
Capacitance is 100uF.
Is our recognition correct?

According to the circuit board above production, input +12V LM22671 input, the output end connected to 1K resistance as a load , but no voltage output?
Other Parts Discussed in Thread: LM22671 I'm trying to use an LM22671 (the fixed 5.0v version) in an automotive (+24v) application to generate a voltage rail at something like +7V. From looking at application notes, it would appear that the minimum…
Other Parts Discussed in Thread: TINA-TI Hi,
I tried to import the spice transient model for LM22671-5.0 in TINA. But it gives me the following error "Invalid Device:$CDNENCSTART. Line #42".
Also I tried simulating the model in Allegro. The basic…
Other Parts Discussed in Thread: LM22671 Hi,
Can I get LM22671 schematic review?
I'd like to use negative output Voltage that is -4.5Vout.
But below circuit's output Voltage is +0.2V measured only...
Could you please check what is wrong?
Thanks…
Other Parts Discussed in Thread: LM22671 I have a design using LM22671. The output needed is about 5V 100mA. Sometimes when the load need some extra current, 10-30mA more, the output of LM22671 has some large & strange voltage swing. I modified the output…
