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…
Hello
It depends on what features and specs the customer is interested in.
I have attached a list of compatible devices that you may want to consider.
Thanks

Can anyone please provide the variation in Feedback Reference Accuracy with respect to temperature (example like -25 degree to 85 and 100 degree) ?
As per the data sheet feedback Reference Accuracy is mentioned as +/-1.5%, but we need particular feedback reference…
I think that the LM22671 is a better choice in this application if you only need 30mA of load. This device has a lower current limit and an adjustable soft-start feature. Both of these will help with inrush current. I have attached a Webench design for…
The data sheet for the LM2596 shows a way to provice a delayed start funcion.
This may be of some help in your application.
If you need a true soft start then you can use the LM2597; this device has an external soft start feature.
You could also use the…

I'm developing a Kintex-7 FPGA board which has to work with both 5V or 27V input voltage.
So far I couldn't choose appropriate power delivering system. I came up with…
Hello Marc,
Consider LM22671MR-ADJ. Configured in the conventional inverting buck boost topology. There is an example late in the datasheet for connection. Also refer to AN-2027 and use either PNP or PMOS level shifter for the Sync signal.
Btw, your typical…
