I recently purchased a 1080P 1200TVL AHD surveillance camera. I wanted a camera that I could connect directly to the AV inputs on my TV so I could view outdoors. I am looking at the AHD to CVBS converter to buy. Would this do the job for me?.....I didn't read fully before clicking the 'PAY NOW' button (silly me)

The NB670 NB670GQ is a fully integrated high frequency synchronous rectified step-down switch mode converter with 3.3V fixed output voltage. It offers very compact solution to achieve 6A continuous output current and 9A peak output current over a wide input supply range with excellent load and line regulation. The NB670 operates at high efficiency over a wide output current load range. Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization.
Under voltage lockout is internally set as 4.65V. An open drain power good signal indicates the output...10-23-2024, 03:23 AM -
I'm trying to fix this Canopus converter so that I can convert lots of old VHS cassettes. The problem is that it turns on for a split (and I mean split!) second, the fan jerks and then.. nothing. I've checked the power brick works. I've opened up the converter itself and been testing for shorts.
The image attached shows the on/off switch (which I've checked works) to the left of the yellow socket. Below the yellow socket is a green block marked 26 with a strange symbol at the front. Putting my probes either end of this block, on the silver parts, gives an open short... -
hi
in an inverter of aircondition i have dc to dc converter mes1515mh
i have attachment the pdf file
can i take a dual converter with two dc outputs instead this ? because i cannot found the same or is not possible ?
the problem is instead 15 volt dc output i have only 6,45 volt
thanks on advancxe... -
zz0.8tpitu4y0i8zzI bought a ch341a (I'm waiting for it to arrive) and I noticed that the programmer has a bug that the data pins go to 5v when the VCC pin is at 3.3v (which is the voltage I'm looking for).
Instead of doing the 3.3v mod, I'm thinking of converting the 5v to 3.3v with an 8 channel TXS0108E through the ZIF socket but I don't know if that would work, because it has to circulate voltage and also information.
What I am looking for is something that will convert from 5v to 3.3v but without modifying the ch341a.
I can't buy the ch341a 1.6v that has... -
You may know this, but all Intel Core CPUs from the fourth generation (Haswell) onwards have an on-die DC-DC converter, and a System on Chip (SOC) which has such is the Broadcom BCM2835 (and certain other SOCs used in the Raspberry Pi) - the only external components for the DC-DC converter are inductor(s) and filter capacitor(s) and in some cases, feedback voltage resistor divider(s).
Do you know of any other SOCs which have an on-die DC-DC converter?
