Dear Members,
I need to design dc dc converter that have input range 30 to 44 volt DC and outputs are 5V @ 3 A, 3.3 V @ 2 Amp and specially low voltage 1 V DC with about 10 AMp capability.
Please guide me for my design. How I can apply Synchronuous rectifier for such low voltage design. If...
Dear Members,
As mechanical engineer support I have to design the Thermal design of custom built enclosure of electronic power supply box.
FR4 Grade PCB on which the power supply circuit has been design and there is a heat spread on PCB is about 18 watts evenly.
This PCB is mounted in the...
Members,
I am in need to design High VOltage Power supply, input is 230V Ac,
then converted to +24V DC by rectifier. and then I need to make DC DC Converter from 24V DC to 1500 V DC. total power will be about 25 to 30 Watts.
Is there useful circuit is available for this type of requirement...
Dear Members,
I am using 3525 PWM IC for DC DC Converter in forward topology for low to medium power buck, I am thinking to switch over to UC3825, current mode converter PWM IC.
Does it worth to switch over to UC3825? Is there any specific advantages? I have tried but face lot of problems in...
Dear Members,
I need to know about PWM controller IC with phase shifted full bridge conveter Controller. UC3875.
My application where input variable 24to 45 and output 28V with high current. Does this controller have problem when input have more input that the output? will not work proper...
Hi members,
I need help on 3825 current mode PWM IC used in forward topology with multi secondaries and DC input variable range.
what are the practical ways for best slope compensation so pwm are stable.
Need tips as in my design after various compensation trial, it does not materialized for...
