I am searching for a 220vac to +5VDC converter / regulator chipset. Can someone suggest of other chip that provides the the given conversion. I've seen one from MAXIM (MAX610, 611, 612), it is a chipset that directly converts 110/220vac to a regulated +5VDC (or even variable 0 to 17VDC) but I still need other options. Can someone (...)
Hi, I need to build 220vac to 12vdc, 100Amps power supply circuit with current limiting. I also need to biuld a 220vac to 3VDC, 100Amps PWM output circuit. Output freq should be adjustable to 50KHz and duty cycle from 0 to 100%. Protection for back emf is required. I shall appreciate any suggestions.
hi any one shall help me to come out the problem. i want to build 230VAC to 12vdc circuit without transformer. i need the circuit diagram and description. regards G R Patil
You haven't specify AC power of the motor .. If ≈500W is enough then here is a low cost 12vdc to 220vac inverter: Regards, IanP
can any one help me with the schematic diagram of a dc to ac converter.That is about 9vdc or 12vdc to approximately 220vac.
i want to build a dc to dc converter with input of 90vdc to 12vdc @2.5 amp
I need the schematic for 15Vdc to 12vdc converter circuit. The converter must have high power rating (more than 100W) so that it can drive various loads from my dc-ac inverter. Please help! >_
Hi, I want to convert from RS232 to RS485, maybe anyone here could help how to do that ( schematic ,etc). I would like to use Maxim IC. Thank you for your assistance.
dears; how to convert 48vdc to 12vdc?
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
100mA is a lot of current for a power supply that is converting from 220vac, if you are not using any transformer. It is also not safe (not for you, because you know what level of safety you have built it to, but concerned for the other users who may not be aware of the lack of safety) unless you are very careful. Small, pre-built power supplies
Hi to all. I'm trying to build a forward convertor (220vac to 12vdc 25A) , but am having a problem with stability. It's a single switch forward converter with a reset winding in the XFMR. I'm using 800V mosfet for switching. The converter is using the old uc3842 controller chip. It is working fine (Nice and stable) at (...)
@ above commenters, some 12V amps (a lot these days actually) pump up the 12V to +/- 50v so that they can do the power advertised. @ThorDruid, to get 12vdc 200A reliably from 220vac requires pretty decent switchmode converters, say 4 x 50A units with the o/p's paralleled, Ebay is your best bet for low $ here.

Hello, i'm intendind to make an NTSC to PAL converter, does anybody know where to find a chip for this pourpose?, i have found a NTSC to RGB and RGB to PAL, so it's possible to do first an NTSC to RGB converter and then convert RGB signal to PAL with the other chip, but i would like to use one chip instead of two thank you very much
I need some help about building ? Voltage to frequency converter. I think I qill use the lm231 from National but I have some question for the input. I need to convert 0v to 40 v and output 0 to 800 hz that look easy. I need to protect the input to a maximum of 300 v without bugs, so I need someting that can bock the tension at 40v, can you help me
