Hi Jeff,
Please also see my previous markup about adding the synchronous rectifier MOSFET as they have in PMP21103.
Since the UCC2987A is made for the active clamp forward topology, you also need to include the active clamp reset MOSFET.
For…
Hello Dattaray,
You can order the EVM on the link below:
The maximum duty cycle of 70% for UCC2897A is considered as a normal operation, you will be fine there.
The paper below has a very thorough approach on how to calculate the power losses…
Hello Mark,
The LM5026 does not have ant integrated OVP function so if you wish to use this part you will need to design in an external OVP circuit. The UCC2897A has an integrated LINEOV function that shuts down the controller in the event of an overvoltage…
slua532.pdf Hi Andy,
I'm sorry about the delay in responding. The UCC2897A is a fixed frequency PWM controller and I am not aware of any application that uses a variable frequency. There is an application report (SLUA532) that describes a burst mode…
Hi Tracy,
We have a application note which can guide you how to design a ACF board with UCC2897A, I attached it for your reference.
Also we have EVM board on line. you can order one to test it . The link as below:
