It operates over a 12V to 17V supply range with a 150 µA startup current, making it efficient for bias supply designs in off-line power supplies. The 6kHz to 220kHz switching range is wide enough to avoid AM radio bands and to optimize the boost inductor for size versus core loss. At the low end, 6kHz allows very small ferrite cores but large winding turns; at 220kHz the inductor shrinks but core losses and gate-drive losses climb. Most designs settle between 50kHz and 100kHz for a practical balance. The frequency is set with a single resistor on the RT pin, so last-minute tweaks are straightforward. ## Lifecycle and supply continuity","metaTitle":"UCC2818D Average Current PFC Controller, 6kHz-220kHz","metaDescription":"UCC2818D average current mode PFC controller from TI.
