What are the key features of UCC28516DWG4?
- Integrated power factor correction and PWM post-regulator in a single 20-pin SOIC reducing solution size
- Current-mode PWM control at up to 230 kHz enabling high-frequency compact transformer designs
- Input voltage range of 10.8V to 15V with 12V nominal for standard bias supply compatibility
- Lead-free RoHS-compliant construction meeting modern environmental regulatory requirements
What is UCC28516DWG4 used for?
The UCC28516DWG4 is designed for use in offline AC-DC power supplies that require both power factor correction and post-regulation in a single controller IC. It is commonly used in server power supplies, industrial SMPS, and LED driver systems where high efficiency and regulatory compliance demand near-unity power factor. The integrated architecture simplifies PCB layout and reduces component count in two-stage PFC-plus-converter topologies.
