Other Parts Discussed in Thread: LM22677 , LM22670 Hello Mr/Ms,
I will use LM22670-adj in topology Buck and inverter together with LM22677 in buck topology (3x CI LM22670 as buck, two CI LM22670 inverter, and one LM22677 as buck). I want to use the pin…
Hello to All
I am using Switching regulator - LM22670-ADJ 3.3V
Power my board Digital and Analog Side.
The for the analog side the 3.3V is filter with ferrite bead 1kOhm@100MHz and decoupling capacitors.
I am measuring some analog sensor - and my ADC …
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

Other Parts Discussed in Thread: LM22670 Hello,
Looking in the Webench, the LM2267x calculator and the data sheet on page 12: “The internal compensation of the -ADJ option is optimized for output voltages below 5V. If an output voltage of 5V or greater…
Other Parts Discussed in Thread: LM22670 , TPS54521 , LM3481 Hello,
I need an inverting switching regulator for the conversion from +5V to -3.3V and a current of 2A. In another application I am using the LM22670 for the conversion from +12V to -5V. Because…
Other Parts Discussed in Thread: LM22670 Hello,
I'm experiencing a 15% to 25% of failures at startup (or shutdown) for LM22670-ADJ. After some minutes it starts to burn and if power is not removed it eventually melts.
Vin=25V, Vout=12V, power consumption…
Other Parts Discussed in Thread: LM22670 Hi
I use an LM22670-5.0 to generate 5V from 12V. I also have a USB input that can supply 5V. I want to connect the USB supply to the 22670 output through a diode with cathode facing the 22670. The idea is that the…
I know this is an old issue but I'm finding I need to make the ESR much larger than expected to tame the cycles down. 0.027 ohms is not quite enough. 0.039 seems barely enough, and 2x that seems better. The webbench design indicates a 15 - 107 mohm…
