Power Factor Correction ICs

UCC28180DR Description

The UCC28180DR from Texas Instruments is an advanced continuous conduction mode (CCM) power factor correction (PFC) controller designed for high-efficiency AC/DC power supplies. Packaged in an 8-SOIC surface-mount form factor, this IC operates within a wide switching frequency range of 18kHz to 250kHz and supports a 21V supply voltage, making it suitable for demanding industrial and commercial applications. With a low startup current of 75µA, it ensures minimal power loss during initialization. Compliant with ROHS3 and REACH standards, the UCC28180DR is ideal for environmentally conscious designs.

UCC28180DR Features

• CCM Operation: Ensures high efficiency and reduced EMI in power conversion systems.
• Wide Frequency Range (18kHz–250kHz): Enables flexible design optimization for various power levels.
• Low Startup Current (75µA): Minimizes standby power consumption.
• 21V Supply Voltage: Supports robust performance in high-voltage applications.
• Surface-Mount 8-SOIC Package: Compact and suitable for automated PCB assembly.
• RoHS3 & REACH Compliant: Meets stringent environmental regulations.
• Moisture Sensitivity Level (MSL) 1: Ensures reliability in humid conditions without baking requirements.

UCC28180DR Applications

The UCC28180DR excels in high-power PFC stages for:
