Part Number: UC3825A Other Parts Discussed in Thread: UC3825 Dear
I used UC3825DW to design a full-bridge power supply ,and the load is a 470Khz amplifer.
when the amplifer works on 70Ws and 100 ohm status, the UC3825 didn't work normally. it's supposed…
Part Number: UC3825A Other Parts Discussed in Thread: LM5045 , UCC28950 Hi,
I am using UC3825DW IC for PWM generation at 350kHz for resonant full bridge inverter . This is operated at 17volts ac. Rc=1.39kOhms and Ct=1.22nF. This IC getting heating up very…
Part Number: UC3825A Hello,
I received the following questions from one of my customers. Please let me know if you need more information. Thank you!
Ilim pin -- Can this be configured for the hiccup over-current/short circuit during startup and normal…
Part Number: UC2825B Other Parts Discussed in Thread: UC3823A , UC3825A , UC2825
I am searching for ways to set up the UC2825B for a flyback converter DC to DC; however, the its datasheet is very generic without pointing into how to set up the circuitry…
Part Number: UC2825B Other Parts Discussed in Thread: UC3823A , UC3825A , UC2825 Team,
My customer has been using this PWM Controller UC2825BN in a flyback converter for 20+ years. They are changing a few parts around this circuitry, especially the switching…
Other Parts Discussed in Thread: UC3825A , UC3825 Hi,
UC3825A is the controller of our buck circuit and the driver IC is ISL6207.
In the application, the input voltage is 20v and the output is 8.4v. the maximum loading is 8A.
During the test, i find that…
Other Parts Discussed in Thread: UC2825A , TL431 Hello,
I'm using the UC2825a for a voltage-controlled halfbridge converter. I need help for the isolated feedback. Because of the 1.25-V-Ramp-offset and the comparator-offset, the output of the integrated…
Is there a way to shut down the IC?
Do I need to set "RAMP" or "ILIM" pins to a voltage higher than 1.25V? Can I do that with a mosfet or transistor without affecting any current-limiting or over-current situations?
Thanks,
Emre
