Part Number: UC3845 Other Parts Discussed in Thread: UC3854 Hi
I am using UC3845 IC for pwm generation for my forward converter. But it is genearting 4 KhZ frequency at Rt/CT pin no 4. but PWM is not generated at pin 6 of UC3854 . what is the reason…
Part Number: UC3845 Currently using UC3845AD which has 0 to 70 degree temp. We need with extended temperature -40degree to +85degree or -40degree to +125degree.
Part Number: UC3845 Dear sir,
i want to required a design uto 250 watt dc to dc converter 12 o/p and 20A o/p current and input range should be 36v to 100 V dc
so sir kindly resolved this design issues and share me
thanks

Part Number: UC3845A Dear Sir,
I design a buck converter Input-40-90V, Output 12V,10A.
I used a Input capacitor 220uF 100V , I face a problem during testing at Input-84V, Output 12V,10A. that the input capacitor is degraded.
why this happned,
pls suggest…
Hi Mr Eric,
I added another 2200uF at the output to make the total capacitance there 4400uF and also,
I tried using 220uF at the output and in the same time increased the CVCC2 capacitor I used 220uF.
But the results are the same with light load (I tried…
Part Number: UC3845 I have attached the schematic as per the ti reference, the output voltage doesn't seems to regulate at 16volt DC output. Whenever a small load is connected the voltage drops to 14.8. at no load the output voltage is 16 volt.
