- Current-mode PWM control enables fast transient response and inherent cycle-by-cycle current limiting
- Wide input voltage range of 10.5V to 21V suits diverse power supply designs
- 20-pin SOIC (R-PDSO-G20) package with lead-free (e4) compliance for modern manufacturing
- Supports high-frequency operation to minimize passive component size in power factor correction stages
Applications
The UCC28070DWR is widely used in AC/DC power supplies requiring high power factor correction, such as server and telecom power systems, industrial motor drives, and high-efficiency LED lighting drivers. Its interleaved dual-channel architecture makes it ideal for designs above 300W where current ripple reduction and efficiency improvement are critical. It is also suited for energy storage systems and EV onboard chargers demanding tight THD control and regulatory compliance.
