The operation of transmitters designed to jam or block wireless communications is a violation of the Communications Act of 1934, as amended ("Act"). See 47 U.S.C. Sections 301, 302a, 333. The Act prohibits any person from willfully or maliciously interfering with the radio communications of any station licensed or authorized under the Act or operated by the U.S. government. 47 U.S.C. Section 333. The manufacture, importation, sale or offer for sale, including advertising, of devices designed to block or jam wireless transmissions is prohibited. 47 U.S.C. Section 302a(b). Parties in violation of these provisions may be subject to the penalties set out in 47 U.S.C. Sections 501-510. Fines for a first offense can range as high as $11,000 for each violation or imprisonment for up to one year, and the device used may also be seized and forfeited to the U.S. government.
Hi Guys - this is an appropriate replacement for the lm2733x and it's power inductor. the lm2733x is NOT suitable for output voltages below 16v!!!
these 2 parts should drop in - but I haven't worked out resistor values yet - please check out the datasheets to confirm I've got this right - it is the LM3731-"Y" notX...
LM2731YMFCT-ND IC CONV BOOST 22V FET SW SOT23-5
308-1500-1-ND POWER INDUCTOR 7.3UH 2.10A SMD
lm2733x does seem to work, with the correct resistor vaules you can adjust right to 5v, but I think at such a low voltagr value that this IC will not handle as much current at all.
Hi there - yes I agree, but the datasheet says 2733x is suitable for 16v and above though, which is why I'm replacing it with 2731y, and a lower inductor - should be drop in replacement for both parts, and the datasheet even gives a 5v example...
I'm going to test out the new 2731y when it get it.
Bbut I'm first going to try leaving the existing one in, and just swap in a 6uh inductor and see how that works.
Hi there - using a new inductor - 7.3uH and the 2731y, I'm getting 5.25v with the same resistors (12k and 39k) as with the 2733x. ie the new inductor and 2731y really are drop in - datasheet says you can get 3.5watts power out...
