That's a wide band: at the low end you can run a high-power PFC stage with larger magnetics and lower switching losses; at the high end you shrink the boost inductor and filter components for a denser layout. The frequency is set by an external resistor and capacitor on the RT/CT pin — no internal oscillator trim, so you pick the trade-off that fits your power budget and board space. ## Package and temperature grade — fit for the BOM The UCC3817N comes in a 16-pin DIP (0.300\" body width, 7.62 mm row spacing) with through-hole leads. The operating temperature range is 0°C to 70°C. ## Lifecycle and sourcing posture The UCC3817N carries an Active lifecycle status from Texas Instruments and is ROHS3 compliant. For a BOM line that needs a through-hole PFC controller, this is a straightforward spec-in — no supply-chain gymnastics.","metaTitle":"UCC3817N PFC Controller, Average Current Mode, 220kHz","metaDescription":"UCC3817N average current mode PFC controller from TI. 12V–17V supply, 6kHz–220kHz switching, 150µA startup, 0°C–70°C.
