2018年10月12日 · The LT3045-A (dual LT3045) board that I linked to delivers 1A continuous output current. Yes, he could use the LT3045A 1A modules as you suggested, but not a standard LT3045 .5A single regulator. It would be an advantage though if he was able to reduce the output of the 9V Linear PSU .

2018年1月15日 · Nothing can change the fact that the wonderful LT3045 is just a 500mA regulator (we use 2 of course and push them a bit to deliver a total 1,100mA). The folks who are paralleling separate LT-3045 boards for more current need to be very careful--with matching to within a few milliVolts--or they will end up with one board bearing much more of the ...

2019年10月28日 · I don’t agree with @Superdad that ILIM based “unique” way of paralleling LT3045 is better and this is the only reason why I don’t use it. I already explained why the statement about his “way to cut the output impedance nearly in half” is a bit tricky (because it is very low absolute values and a minor part of the full impedance ...

2018年9月12日 · The beloved LT3045 does provide AC impedance, well either the AC ripple is shunted to ground or blocked via impedance (depending on the exact circuit). So of course the LT3045 will provide additional impedance to AC currents ie PSRR.

2020年3月25日 · 6: Two LT3045 based adjustable rail max current has been increased from 2A to 3A per rail by adding two additional LT3045 for each rail. This is a 50% increase. 12pcs LT3045 are used in 300W LPSU compare to 8pcs in the 200W LPSU. 7. Over temperature protection is added to the 300W LPSU. The cut-off temperature is set at 80C.

2018年12月30日 · One Hdplex LT3045 output was used at 15 volts to the HPULN and disk enclosure. The wifi extender on an entirely different LPS, left me free to power the NUC with either the Hdplex LT3045 at 15 volts or easily switch to the Hdplex 19 volt output. Both sound great, but the 19 volt output was richer in a big way.

2017年1月20日 · The LT3045 1A PCB would be dropping too much voltage (7v at 1A = 7W of heat to dissipate) when used on it's own to provide +5V from an internal +12V supply rail, so would not be suitable for use internally. Even the more typical current draw of around 500mA from an SSD would see it dissipating 3.5W of heat.

2018年1月15日 · 4) Thus the paralleled pair of high PSRR, ultra-low-noise, ultra-low-output impedance, Linear Technology LT3045 regulators is always fed with a pure voltage that is 1V above whatever the output setting is.

2018年6月24日 · LT3045’s input and ground terminals, the use of low value input capacitors combined with a large load current can result in instability. The resonant LC tank circuit formed by the wire inductance and the input capacitor is the cause and not because of LT3045’s instability.
