How to control NCP5623C , any sample code (.c or .cpp) for refernece ? Thanks 44 2015-06-18 10:35:55.619
I am interested in the CMOS sensor LUPA 1300-2 (NOIL2SM1300A-GDC-ND) for a research project. Because of the nature of the project I need to know whether you have an evaluation kit that works with that sensor. I would like to vary parameters as frame rate, selection of ROIs, image format, etc. Is this available? Also, I would like to have more information about what drives/powers or controls the sensor (e.g. FPGA development board, installation software included, etc. and if so provide part numbers please) . Finally, a picture of the sensor and its associated equipment would be good to know whether the sensor can be incorporated into another system. Thanks 46 2015-06-16 13:38:07.432
I want to manufacture a simple12 Watt LED bulb (B-22) for residential application. I need technical guidance on selection of SMD LEDs, number of LEDs, the best layout in series OR Parallel OR Multiple series parallel cross-connect combination. I need technical guidance on selection of Constant current driver for the same bulb. The driver should be well designed with high power factor (0.9) with built in power factor correction, low harmonics distortion value, surge voltage protection. 64 2015-06-08 14:11:21.634
Where can I find photos of your CMOS image sensors, e.g., the PYTHON500, AR0141CS, MT9V115-D? What would samples cost? 76 2015-06-05 03:20:35.994
Madam/Sir, Kindly give the details about the recommended magnetics to be used with the LV5012MD-AH for 2800mA application with 100V which is approximately 300 Watt. 174 2015-04-08 11:05:16.963
Does anyone has a formular for calculating 431...thanks in advanced if you can send to me. 210 2015-03-27 15:20:30.483
how i design the flyback transformer ? and what are the parameter i required to design a flyback transformer for led driver application. can you provide me the pdf document to learn how we design the flyback transformer? and how we check the transformer , is it ok or not? 216 2015-03-23 13:10:10.35
I recently moved into a new house where the rooms have got dimmer switches with Halogen bulbs. I would like to replace the Halogen bulbs with LED bulbs. How do I know if the LED bulbs will work with the existing dimmer switches? will it be trial and error or do I need to buy a special dimmer module? Thanks in advance 244 2015-03-10 14:48:52.329
Good day! Can you recomen desighn to LED Driver 150-500W Full-Bridge + SynchRect Now customer thinc about UСС28083D ore UCC28950 289 2015-02-20 12:58:23.253
Hello, I'm interesting by the CAT4104 for my new design. In the datasheet, I read this : 1 - "Accurate linear dimming is compatible with PWM frequencies from 100 Hz to 5 kHz for PWM duty cycle down to 1%.". 2 - Maximum EN/PWM high time = 5us Does it mean that : - if my PWM frequency is 5kHz, the minimum duty cycle is 1% but if my PWM frequency is 1kHz, the minimum duty cycle can be 0.2% ? OR - the minimum duty cycle is 1% from 100Hz to 5kHz ? Thank you in advance. 277 2015-02-18 13:20:29.683
I am using your current driver NUD4001DR2G, I have an application requiring 750ma constant currant, looking at the data sheet fig. 7 is what I'm after, combining 2 500ma drivers together to share the current load Question how is the Rext (current set resistor) calculated in this application? Second question, what is the purpose of D1? 597 2014-12-16 14:26:05.514
I wanted your support for IC selection for dimmable (PWM) driver design. one of the important requirement is to support up to 305V AC input. Please suggest the best possible option from ON Semiconductor considering this requirement. I look forward to hear from you promptly. Also, send me updated ON Semiconductor presentation for my quick reference. 514 2014-12-10 12:38:26.473

MURA210T3G diode. Does the anode pad or cathode pad get hottest and require more heatsinking? 902 2014-06-03 15:10:34.763
How to connect 2 or more power LEDs having different operating voltages (3.5v,13.6v) for an input range of(6v to 36v).I will connect one LED at a time to a circuit but the circuit should support for both the LEDs. 1183 2014-03-05 10:24:56.455
Please tell what's the difference between MC74LCX244DTG & MC74LCX244DTR 1358 2013-10-25 11:24:42.335
is NCP 3066 suitable to be used to Run an osram Golden dragon plus LED from a single call Lithium Phosphate ? if so what is the circuit to archive this? 1602 2013-09-17 14:42:42.927
Dear, Now my project use the IC CAT3604VHV4-GT2, but there are some questions about it. First, there is no ESD specification in the datasheet. I want to know the ESD parameter. Second, this IC is in mass production. I want to know whether there is the plan about stopping production or not. Or which life schedule the IC is? Or when will the IC stop production? I am looking forward to you. TKS. 1510 2013-06-06 14:33:41.681
I'm constructing an art exhibit using CAT4013 RGB Drivers. I have so far been unsuccessful in programming my FPGA, using VHDL, as a controller. Is there any example code for this driver? 1861 2013-04-09 10:01:14.944

I am using the MC33262DR2G to control a flyback power supply in an LED lighting application. During overstress temperature testing I ran the LEB lamps in a thermal chamber to temperatures over 100C. At some point the lamp went out. Later, when I cooled the unit and reapplied power the lamp came back on. My question: Is there a thermal over temperature circuit that would shut the MC33262DR2G off at high junction temperature such as 150 C? I do not see this in the datasheet, but would like to find out if there is an undocumented over temperature shutdown feature. Please send my any available information. 2144 2011-06-15 17:54:39.0
