Part Number: UCC3800 Other Parts Discussed in Thread: UCC2801 , UCC2805 , UCC2804 , UCC2802 , UCC2800 Dear seniors,
I want to use UCC3800 to make a 2W flyback power supply.
Because the input voltage range is narrow, about 11.5V~12.5V, and the output voltage…
Other Parts Discussed in Thread: UCC3800 Hello,
I have a few questions concerning the overcurrent feature of the UCC3800:
Is it safe to pull CS up to 5V in order to shutdown the output? It seems like it is triggering the current limit comparator but not…
I would like to know if shorting Vref to ground will cause any damage or if there are any long term reliability concerns. I would like to use the Vref to shut down the PWM chip.
Thanks,

Part Number: UCC3808-2 Hello everyone,
I am using the UCC3808 controller in a Push-Pull Topology. As the duty cycle at steady state would be greater than 50% it is almost imperative the use of slope compensation. The circuitry that I am using to achieve…
Hello Kaji@PAN,
Thank you for your interest in TI Parts. Other Low power BiCMOS: CMPWM that would fit these specifications are UCC2800/UCC1800/UCC3800.
I am attaching the link to a search on ti.com for similar parts, this list will be a good starting…
Other Parts Discussed in Thread: UCC3800 I want to design smps with input 8-30 V and output must be 12V 1.5 A 18W. Please suggest me the IC and please suggest me the reference design.
Other Parts Discussed in Thread: UCC2806 , UC1846 , UC2846 , UCC3800 I could not find a pspice model for UCC2806 on TI website. Does anybody know how to get it?
