Posted on July 19, 2013 at 05:44How to Control the SCR with Microcontroller. I dont want to mix the Digital Signal Ground with the High Voltage Ground. But the SCR will need the Gate current in uA w.r.t its Cathode. But I couldnot connect the Cathod...
Posted on March 08, 2015 at 12:10 I have simple question about snubberless triac. When it is said that the triac is snubberless do still need an external snubber circuit?
Posted on December 01, 2016 at 00:27 After reading AN3168 I found a paragraph that I do not actually understand and seemed weird for me . Page 8, ''With the bipolar solution, to keep the current sourced to the gate, the only way is then to use a PN...
Posted on October 12, 2015 at 20:29I need to support a 2-wire 500W dimmer instead of just a 300W dimmer at 110VAC 60Hz US. What are the power limiting components of the ST Dev Kit? The 2 1N5404 diodes are only rated for 3A which would be 360W. Is th...
Posted on November 30, 2016 at 23:34What is the formula for Vo vs ADJ? Or in other words, how should R1 and R2 be chosen to get a specific output voltage?The data sheet, DocID025199 Rev 2, does not appear to include the necessary formula or ratio.
Posted on January 26, 2016 at 15:16Has anyone been able to read the fault register. I have no problem reading back set-up, but fault is hidden. RichA #l99sd01
Posted on November 22, 2016 at 05:42Can anybody suggest me reference design for driving LEDs array along with micro controller.Here is my requirement :- Output 1 :- 17V, 400mA (Constant Current)Output 2 :- 3.3V, 1A (Constant Voltage)Power :- 12WIs...
Posted on November 14, 2016 at 19:08Hi There,We would like to design a Wide Mains, HPF, PSR, CV 25V 11W power supply using the HVLED815PF, however the eDesignSuite only allows to use it as a LED driver (constant current). There is an application not...
Posted on November 07, 2016 at 21:21I bought VNH3SP30 a few years ago and recently used them in my self design board.I want to drive it by 3~5 KHz PWM freq. based on its spec. (Up to 10KHz as mentioned in its Datasheet). but when apply upper 1KHz PW...
