Part Number: UC3525A Tool/software: Hi Eric
What values of RT and CT should we choose for a fixed OSC output frequency of 190KHZ with an accuracy of 6% ? RD=0
In our current application, RT=4.22k and CT= 1.5nF, RD=0 , which gives a calculated value…
Part Number: UC3525A Hi Team,
Please refer to the schematic,
Customers use UC3525 to create push-pull topology; CH1: Vo (yellow) CH2: COMP (pin 9/green) CH3: OP+ terminal (pin 2/blue) CH4: OP - terminal (pin 1/red)
Under normal circumstances, pin4…

Part Number: UC3525A Tool/software: Hi,
I want to use and external error amplifier based on Op-amp in order to achive Type -3 compensation and variable reference volatge to get variable output voltage from a buck converter. Is there any way to disable…
Part Number: UC3525A Other Parts Discussed in Thread: STRIKE , , UCC28C45 Dear All,
Me too. I would like to create Tina SPICE model of UC3525. Anybody knows which way is possible create this IC macro model using discrete componnents? On the data sheet…
Part Number: UC3525A Tool/software: Hi, I am trying to generate PWM with 10KHz frequency and trying to very duty cycle less than 1% . However below 1% of duty cycle that is 1us the pulse becomes unstable, weak and dies down.
I am using external DC variable…

I have seen a design that sets the INV and NON INV pins to fixed level, INV to GND and NON-INV to VREF. Then the COMP pin 9 is Pulled to Vref via resistor. Pin 9 is then adjusted to gnd to adjust PWM.
My question…
Part Number: UC3525A Hi, I'm going to design a half bridge to be used in the charging station. I will use UC3525 ICs in half bridge. When using these ICs, should I do the calculations according to Continuous Conduction Mode or Discontinuous Conduction…

Hi
We're using UC3525A PWM IC, we observed abnormal current spike in mosfet drain current and it is causing mosfet. please look into below ref images and give us solution for eliminating current spikes.
Best regards,
