What are the key features of UCC28500DWG4?
- Integrated PFC pre-regulator and PWM post-regulator controller reduce total IC count in off-line power supply designs
- Programmable for current-mode or voltage-mode PWM control, offering design flexibility for various converter topologies
- 115 kHz maximum switching frequency enables use of smaller magnetic components, reducing transformer and inductor size and cost
- 10.3 V to 15 V input voltage range with 12 V nominal supply ensures compatibility with standard bias rails in AC-DC power supplies
What is UCC28500DWG4 used for?
The UCC28500DWG4 is designed for use in off-line AC-DC power supplies that require both power factor correction and regulated DC output in a single control stage. It is well suited for computer power supplies, industrial SMPS units, and LED driver power stages where meeting EN 61000-3-2 harmonic current limits is mandatory. The device's flexible control mode programming also makes it attractive for telecom rectifiers and medical power supply designers who need to optimize efficiency across a range of load conditions.

Frequently Asked Questions
Which offline power-supply designs can use UCC28500DWG4 as a combined controller?
It targets high-efficiency offline supplies needing power-factor correction plus PWM control, with operation from 10.3 V to 15 V and control up to 115 kHz.
How flexible is the control approach for new or legacy power stages?
The controller supports current-mode, voltage-mode, and PFC control, so engineers can adapt one 20-pin SOIC device across several offline converter architectures.
What lifecycle risk should procurement consider for this TI controller?
Because the fetched lifecycle status is obsolete, buyers should plan approved alternates and last-time supply coverage around the 20-pin SOIC footprint.
