Part Number: UCC2893 Hi E2E,
Good Day!
We just wanted to check the maximum ambient temperature it can have?
Based on the datasheet, page 2 http://www.ti.com/lit/ds/symlink/ucc2893.pdf temperature is -40 to 125 degree C
But on the website, http://www.ti.com…
Part Number: TPS7H5003-SP Other Parts Discussed in Thread: UCC2894 , UCC2893 , UCC28780 We'd like to adopt the flyback converter with PWM active clamp.
So far , we are used UCC2893 or UCC2894 .
At happens , we found the TPS7H000*.
We can design active…
Hi Tak-San,
Thank you for the reply.
Question 2) I think from your input voltage specification of 85 to 264Vac and using TPA3251 I assume power level around 160-220W for your application. So UCC28780 should be good for this power levels. Are you generating…
Part Number: UCC2894 Other Parts Discussed in Thread: UCC2891 , UCC2893 , UCC2897A Hi Sir,
As per the datasheet of UCC2894, Vdd supply is taken from the output side filter inductor, the screenshot is give below for the quick reference.
Can we take the…
Hello Mitesh,
Thank you for your interest in TI's active-clamp controllers.
The UCC28780 can work at the higher voltage of your range, but is likely to have trouble at the 14-V end. Notably, it needs at least 17.5V to start (actually 18.2V max).

Hi Denny,
The UCC2897A has the following summary and 20-pin TSSOP pinout
The UCC289x family has the following summary and 16-pin TSSOP pinout
I would recommend either the UCC2891 (P-channel clamp) or UCC2893 (N-channel clamp) because they both offer…
Other Parts Discussed in Thread: UCC2893 , UCC2897A , TPS2410 Hi,
My name is Guilherme Muller and I’m developing a step-down SMPS using UCC2893 from Texas. My benchmark is ~90% of efficiency, so I’m using an active clamp forward converter with synchronous…
