UCC29910A: AC/DC reference design

Michael Unneback
Prodigy 20 points
Part Number: UCC29910A
Other Parts Discussed in Thread: UCC29910, UCC29900,

The datasheet for UCC29910 mention a reference design for a laptop power supply.

Text from datasheet:

A fully characterised reference design using the UCC29910A PFC controller and the UCC29900 Integral Cycle Controller is available on request.

How to request this reference design ?

thanks

/Michael

    Hi Michael,

    Thank you for your interest in the UCC29910A PFC controller. I have contacted the applications engineering team for this device and requested they provide the reference design to you. Please allow a business day or so to hear back.

    Regards,

    - Daniel

    Hi Michael,

    The reference design refers to UCC29910AEVM-730, you can order from TI website: www.ti.com/.../ucc29910aevm-730

    Hi,

    i already have looked on that reference board. There seems to be also a reference design for a 90W slimline notebook-adaptor.
    Referred to as “90WHD”

    From TI doc "Power Factor Correction Using the Buck Topology—Efficiency Benefits and Practical Design Considerations"

    vII. Buck Pfc Performance revIew:

    90-w Adapter reference design
    The buck PFC has been deployed as the PFC
    front-end in a 90-W, high-density, slimline
    notebook-adapter reference design (referred to as
    “90WHD”). This two-stage design uses a halfbridge
    isolation/regulation stage to down-convert
    the buck PFC bus voltage to an isolated and
    regulated 19.5-V output voltage [16]. Fig. 23 shows
    a simplified block diagram of the buck PFC powerstage
    topology as deployed in this design based on
    a dedicated buck PFC controller, UCC29910.

    Hi Michael,

    I agree with the research you have done on this "90WHD" (and I have researched an equivalent design based on the UCC29910) material and the reference design does not exist even though it is referred in the UCC29910 datasheet as well as the 2010 Power Supply Design Seminar paper for SEM1900 Topic 4. This reference design is not available but I did find some information dated back to 2009 that may be of interest to you. Send your email/contact information to b-Johnson@ti.com and I can forward you the information I have uncovered that may help you design your own power supply.
