UCC28089DG4 Description
A high-performance active power factor correction (PFC) controller made for AC-DC power supply applications is the UCC28089DG4. The gadget works in critical conduction mode (CRM), which enables it to maintain a stable output voltage while achieving high efficiency and low electromagnetic interference (EMI).
The UCC28089DG4 includes a comprehensive set of protection features, including over-voltage protection, over-current protection, and thermal shutdown, which assist assure dependable and secure operation. These features are in addition to its sophisticated PFC capabilities.
UCC28089DG4 Features
Frequency jittering feature to reduce EMI noise.
Available in a small outline, low profile package.
Internal driver for MOSFET or IGBT power switches.
Supports universal AC input voltage range from 85 VAC to 265 VAC.
Soft-start and soft-stop functions to prevent output voltage overshoot and over-stress of power components.
Comprehensive protection features, including over-voltage protection, over-current protection, and thermal shutdown.
Pin-compatible with other members of the UCC2808x family of PFC controllers for easy upgrade of existing power supplies.
Power management features, such as dynamic frequency adjustment and burst-mode operation, to optimize power consumption and reduce heat dissipation.
Critical conduction mode (CRM) operation, which enables high efficiency and low electromagnetic interference (EMI) while maintaining a stable output voltage.
