Part Number: UCC24636 Other Parts Discussed in Thread: UCC24624 Dear Team,
our customer uses the UCC24636 for an industrial battery charger. The first version had an output voltage of 11-15.6V, so no problem.
In another project they are looking for a SR…
Part Number: PMP15002 Other Parts Discussed in Thread: UCC24636 , UCC28704 , UCC28700 , , UCC24610 Hi
My customer will design 12W power surpply with high efficiency and small footprint. they think using UCC28704 or UCC28700 and UCC24636. I found PMP15002…
Other Parts Discussed in Thread: UCC24636 Our customer is designing a UCC24636 application.
He asked how dose UCC26363 work when entered into the CCM mode condition caused by an abnormal operation such as an over load.
Of cause it has been designed in…
Other Parts Discussed in Thread: UCC24630 , UCC24636 , UCC24610 , UCD3138 I received this question from the field recently:
Can UCC24630 or UCC24636 be used as Synchronous rectifier (SR) controller for LLC?
Hi Charles,
The UCC28781 or UCC28782 could work for this. For the PFC, the UCC28056 can be used on the front end.
I found PMP22538 which is a 60-W reference design that might be a good starting point as well.
WEBENCH recommends an LLC approach which would…
Other Parts Discussed in Thread: UCC24630 , UCC24636 Dear Sir,
I received this question from my customer.
Can UCC24630 or UCC24636 be used with two or more secondary side FETs in parallel configuration?

Hello Jack,
Thank you for your interest in TI controllers.
For your ACF and QR applications with SR, I suggest that you review the UCC24612 SR controller datasheet https://www.ti.com/lit/gpn/ucc24612 . This is probably your best bet.
Another option to consider…
Hi, SongZhen:
Thanks for your feedback.
What is the waveform in Green?
And the VS waveform seems wired to me. It is almost like a tringle. The correct Vs should be as below, and Vs should be around 4V as normal operation. (spike is not included)
Maybe…
Hi Zixuan:
Please check the reply as below.
1) UCC24636 is only for DCM and transition mode operation. It does not support CCM. Also, it only support max frequency is 130kHz. UCC24630 supports 200kHz. Hence, if you are going to design a CCM flyback or…
