I need paper or schematic about RF to DC converter. if you have, please upload . Thanks in advance
Hi good day everyone! Can anyone help me simulate the RF to DC converter circuit that I have created in Agilent ADS? I want to know the output voltage given an input frequency (915 Mhz) and also the correct specs like the width and length for my microstrip design? THank you
hi all....i'am study about RF to DC converter..i need some advice how to design RF to DC converter..i also asking any example of RF-DC circuit that will produce 5v of DC output.. thanks
You could use voltage multiplier if your sensor does not need too much current. Give us data: RF frequency, RF power level, required DC voltage and load current.
hi all, I want the DC to DC converter IC. The input voltage is 5V and the output voltage is +/-3.3V and (minimum)150mA (maximum)250mA. I came to know that this type of converter is available in Texas. Can any one help me in finding this. It was very urgent Thanx all.

Hi all, Can any one know any thing about DC-to-DC converter (or) Buck converter?. Plz help. Thanx.
Dear all, I measure my dc to dc converter ( 3.3 -> 1.8 ) . My design is load current is 0.8A. But I measure my output will have a spike at load current of over 0.4A. This spike will be sometime the peak of 2.8. This condition my OCP is off. Why do my load current can not over 0.4A? The other question. Is it load current is l
Hi everyone, Can any body present here may help me in understanding and making a UPS based on SMPS AC to DC converter so that there will be no need of any type of transformer and the UPS would not be bulky and heavy. It should handle be capable of handling atleast 500Watts of Power. Thanks in advance

Hello All, I am using a optical module that required 5, 3.3 and -5.2V. the current needed at the -5.2 V rail is 4A, I was searching a -5.2V non-isolated DC to DC converter with an output current up to 4A I did not find any because the input voltage to this non-isolated DC to DC converter is 5V (the board have only a single 5 V supply). I am p
Can someone suggest to me a multiple input AC to DC converter module or chipset that converts 220Vac to 5Vdc. The scenario is this, in a control panel, there are lamp indicators that lights up upon completion of each process (flood control process) i need to detect each lamp indicator as it activates so that I could remotely control each device
Hi. Ya'll My chip of wireless sensors will be fed by RF signal (by inductive coils). I am now stuck at design for RF to DC regulator (2.5V VDD generation). My charge pump multiplies voltage and provides unregulated DC with small ripples. This DC varies from 0 to upto15v depending on the distance between the transponder and reader. My CMOS onl
Hi good day. I am using some 6Volt batteries that you can pickup at walmart, to get either 12V dc or 18V dc. I was wondering if there is a way to achieve the same outcome using an AC/DC converter. When I search the net looking for a converter there are just too many to understand what will work similar to 2 or 3 6Volt batteries in series. Any idea

Hi All, I am looking for really small ac to dc converter(would be really good if its made using cmos process) that can operate at 13-19 Mhz and can provide output voltage of 2.8 volt. I need this type of converter as i am working on wireless energy transfer using inductive coupling, any help is appreciated. Thanks
Lots of ics available that will do what you want. An example is LT1680, the datasheet shows an example circuit (use it with a couple of IRFZ44 or similar), and also shows the formula for computing the values to meet your voltage requirements. Bear in mind a car battery is seldom 12V, but varies. Use a varistor at the input, and maybe a TVS too.

I asked about DC to DC converter and I got the answer that "when we need different dc voltages and need higher amperage from low amperage batteries we use DC to DC converters like in Laptops" My question isn't possible that we get different AC voltage levels from transformer and simply convert them to DC. As we know the purpose of using AC si
