It switches between 80 kHz and 120 kHz, covering the typical range for offline PFC stages in switch-mode supplies, ballasts, and front-end converters. The 10 V to 20 V supply range lets it run from an auxiliary winding or a simple bias rail, and the 250 µA startup current keeps the start-up resistor dissipation low. ## Lifecycle and sourcing — active and available The UC2854BQ-TI carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy or obsolescence notice is in effect. For BOM lines that need this specific Average Current Mode PFC controller, it remains a current-production part — no forced redesign.","metaTitle":"UC2854BQ-TI PFC Controller, Average Current Mode, 80-120 kHz","metaDescription":"UC2854BQ-TI is an active PFC controller from TI in 20-PLCC package.
