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.
