Dear support,
On my adjustable output voltage application I currently use the LM2678SX-ADJ reference but I would need some alternative references.
Can the LM2677…
Part Number: LM22677 hi all,
I have a customer using the LM22677 and facing a problem that (in my opinion) looks like an OTP.
Unfortunately this part is very old and the datasheet is not one of the best, so I wanted to double check with you my tough was…
Part Number: LM22677 I'm developing a power supply that should range between 1.5V ~ 18Vdc using LM22677TJ-ADJ / NOPB and a micro controller. I have success when the output voltage is between 3.5 ~ 18V with the load consuming between 1 ~ 2A, but when…

HI,
we are trying designa buck using LM22677 part wit an input rage from 20-30V and output of 15V 0.5A but webench is throughing design based on LM22677-5.0 but we it should provide design based lm22677-adj…
We currently purchase the LM22677-5 but I need to reduce the output to ~4V. Is the feedback pin still attached internally? Can I just put a resistor to GND and reduce the output?
Thanks.
Other Parts Discussed in Thread: LM22677 Hi team,
I am using the LM22677 and simulating on WEBENCH with an output voltages 8V and 30V and massaging the component values until there is one solution for both outputs. The WEBENCH solutions point to the LM22677…
Other Parts Discussed in Thread: LM22677 Hi,
I have problem with the Lm22677.
Attached you can find the circuit diagram.
The Vout (C39) reaches 3.8V (rms) with a ripple of 300mV, instead of 3.4V
The rms value for the FB is over the datasheet range (1.45V…
Other Parts Discussed in Thread: LM22677 Hi,
Here's the design report for LM22677 Vin(30v min/38V max) Vout(12V) Iout(4A)
(please see the attached pdf.file)
As for the output Voltage setting resistor value, RFB1=787Ω、RFB2=1kΩ are chosen.…
Other Parts Discussed in Thread: LM22677 , LM5576 Hi,
I would like to operate two LM22677's driving separate loads both at the same voltage. One would be on continuously and the other would be commandable ON/OFF as needed. When both were on, the slave should…
