Hi,
It looks UCC2808A-1, or -2 OUTA and OUTB should produce similar - what difference do you see from UCC2808A-1, or -2 that cannot meet your requirements?
TL494 maybe another device can be considered.
Part Number: UCC2808-1 Other Parts Discussed in Thread: UCC2808A-1 , Do we have TINA SPICE Model for UCC2808-1 and UCC2808A-1? If not what is the nearest equivalent part available. I want to simulation Isolated DC DC Conveter Push Pull Topology 300KHz…
Part Number: UCC2897A Other Parts Discussed in Thread: UCC2808A-1 , UCC2808A-2 Dear TI team, We have below requirement, Could you please go through it and suggest us best possible part number from TI. Requirement: Input voltage : 20- 35 ( Nor 28V) DC…
Hi,
Our solution is PWM controller + Driver. For 600V applications, driver UCC27712 can be used along with a PWM controller, such as UCC2808A-1 or -2 which is ok to operate in open-loop.
Part Number: UCC3808A-2 Other Parts Discussed in Thread: TL431 Tool/software: Hello:
We are designing with the UCC3808A-2 for proto. We are aware that this part will be obsoleted and replaced by a similar pat with different marking.
Will the new part…
Part Number: UCC2808-2 Other Parts Discussed in Thread: UCC2808-1 Hi,
I use the chip UCC2808-2 and I would like to fix the duty cycle about ~40%. How to do it ?
I'm confused with COMP and CS pins functionnality. I read that "The CS pin is for duty…
Hi Kato-san,
You can consider using the UCC28C44 or the UCC2808A, family of parts.

Hi James,
Vin is very low at 9V the input current will be something like 55A or higher to allow for power dissipation through the power stage.
Most customers use push-pull topology for higher powers in this voltage range.
UCC2808A is an option,…
Hello Watchaphong,
You could use the LM5030 for such an application however 100kHz is below the minimum operating oscillator frequency of the ic.
You should consider using the UCC2808A-1 or the UCC2808A-2 which is another push pull controller and…
