Muhammad Abu Bakar Posted April 22, 2006 Report Posted April 22, 2006 YOU can have a very cheap power supply from TI's Isolated DC/DC Converter IC's Series. One such chip isPT4310 Series —48V 6-W Low-Profile Dual-Output Isolated DC/DC Converter Its main features include• Dual Complimentary Outputs• Wide Input Voltage: 38 V to 75 V• 1,500 VDC Isolation• 9 Pin DIP Package• No External Components RequiredAs TI people are very generous in distributing there samples, so u can have a sophisticated lab Power Supply with almost no effort.Regards :) :) :) Quote
ante Posted April 22, 2006 Report Posted April 22, 2006 Hi,I don’t understand what you mean. Can you provide the information and circuit diagram of how to build a “sophisticated lab Power Supply” with one of these converters please?Thank you! :) Quote
Muhammad Abu Bakar Posted April 22, 2006 Author Report Posted April 22, 2006 I tried this circuit. Quote
ante Posted April 22, 2006 Report Posted April 22, 2006 Hi,Oh, I see! But I would not call that a “sophisticated lab Power Supply”! I would expect a lot more from such a device! :-\ Quote
windoze killa Posted April 24, 2006 Report Posted April 24, 2006 Well I think this could be a bit of a language missunderstanding. I would probably consider this to be sophisticated in as much as it is all in one and not agricultural having 50 discrete components. I think Ante maybe confusing sophisticated with complex. Quote
audioguru Posted April 24, 2006 Report Posted April 24, 2006 It is not a sophisticated lab power supply circuit.1) It has hardly any output current.2) Its voltage regulation is not nearly as good as other voltage regulator ICs.An LM317 is sophisticated and is complex internally but its circuit is simple externally. It works much better. Quote
ante Posted April 25, 2006 Report Posted April 25, 2006 I consider “sophisticated” to be somewhat “advanced” which I do not think this is!I also do not understand what farming terms like “agricultural” have to do with this! ??? Quote
Muhammad Abu Bakar Posted April 25, 2006 Author Report Posted April 25, 2006 Actually I am annoyed with those bulky high current transformers. Therefore any circuit which doesn't require a transformer is a SOPHISTICATED circuit to me. I am looking for high capacity, high voltage non-polar caps to increase current capability. Quote
audioguru Posted April 25, 2006 Report Posted April 25, 2006 You are looking for an expensive, bulky and dangerous capacitor that won't last very long to replace a very safe and reliable transformer. Quote
windoze killa Posted April 25, 2006 Report Posted April 25, 2006 I consider “sophisticated” to be somewhat “advanced” which I do not think this is!I also do not understand what farming terms like “agricultural” have to do with this! ???I think this device is advanced compared to a 7812. As Muhammad says there is no need for a transformer so compared to older style powersupply modules thats pretty advanced.And agricultural just means thrown together or bread boarded type construction. Maybe a bit of an Australianism. Quote
ante Posted April 26, 2006 Report Posted April 26, 2006 Ok, ozzy strine then! Yeah, I see you’re a bloke from down under, should have known! ;D Quote
windoze killa Posted April 26, 2006 Report Posted April 26, 2006 Ok, ozzy strine then! Yeah, I see you’re a bloke from down under, should have known! ;DLucky we are thick skinned to.And before the rest of you try to be smart that doesn't translate into thick head. ;D Quote
