Frequently Asked Questions
Which power-supply control designs are a good fit for UCC28528DWG4 at 230 kHz?
UCC28528DWG4 suits AC-DC supplies that need power-factor correction plus a PWM post regulator, with current-mode control and a 230 kHz switching frequency for compact magnetics.
How should the 10.6 V to 15 V input range shape the controller bias supply?
Designers should keep the controller bias within the 10.6 V to 15 V operating input range, with margin below the listed 18 V maximum supply condition.
For PCB layout reviews, what does the 20-pin package mean for routing and sourcing?
The device uses a 20-pin SOIC-family package, so buyers should align footprint, pin escape routing, and alternate-source checks around the same 20 pins and gull-wing assembly format.
