I want a Flashing LED driver circuit ushing Linear constant current LED Driver Part No BCR421UW6-7. (1) The input to the driver circuit can be anything between 15V to 35V DC. (2) There will be six LED driver ICs part No BCR421UW6-7. (3) Each LED driver will produce 350mA current to drive a string of 4 LEDs (forward voltage 3.1V) connected in series. (4) There will be a mechanism (using a 555 timer) to enable the LED drivers ON-OFF at rate of 50 pulses per minute. (5) Input Reverse polarity protection shall be provided using a Diode on the Positive supply pin. The freelancer shall: (1) Design the schematic. (2) Generate the PCB with proper vias and other mechanisms for thermal management (as drivers will generate lot of heat). (3) Deliver: (i) Schematic, (ii) gerber, (iii) BOM Payment terms: (1) 15% on Schematic (2) 25% on Gerber and BOM (3) 60% on successful testing of board. Freelancer Attributes: - Ideal candidates should have experience in electronic design specifically focused on LED technology. - Precise skill set required includes knowledge of simulation, schematic and PCB gerber generation. - Adequate thermal management skills in the PCB is a must.

You literally can't dissipate lot of wasted energy as heat. For ex one string will dissipate around 8W at max 35V supply. So in total 32Watts. Also the LED will produce some heat as well. So I think either you need a buck converter to drop the voltage to somewhere 13V or use switching mode LED drivers. We can discuss about this plan if you are interested on the price. Let get in touch to discuss further. Thanks
