Part Number: UCC2897A Other Parts Discussed in Thread: LM5026 , , UCC24612 Hello TI experts:
Input: 36~75V
Output: 12V 72V
The design is expected to use UCC2897A (Active Clamp forward) at 350kHz.
Would you recommend using UCC24612 as the SR IC?
Or do…
Part Number: UCC2897A Other Parts Discussed in Thread: PMP8861 Hello TI Support Team,
I am designing an isolated DC-DC converter using the UCC2897A controller, based on the PMP8861 reference design. The converter operates correctly over the full input…
Part Number: UCC2897A Other Parts Discussed in Thread: UCC28C43 I'm considering designing a ZVS flyback converter based on the UCC2897A. I'm looking for low EMI, hence this choice.
General assumptions:
Vin = 24VDC +-10% Vo = 19V Io = 1.2A Galvanic…

Hi, I am simulation the IC in simmetrix. Secondary voltage is regulated as required.But,i see,Gate pulses toggling two to four times before actuall yturned off in simulation as shown below (green). AUX gate pulses is ok.CS voltage…
Part Number: UCC2897A Hi Team,
we are using UCC2897A Advanced Current-Mode Active-Clamp PWM Controller to genrate 12V from 54V DC input. We could see Vout is only 3.3V against the actual 12V output.
On further analysis we identified VCC_OUT supply…
