It provides two transistor-driver outputs with a 75% maximum duty cycle and a 200kHz to 2MHz switching frequency range. ## Switching frequency and duty cycle — what they mean for the transformer The 200kHz to 2MHz range lets you trade off transformer size against switching losses. At the low end, you get wider flux swing and simpler magnetics; at 2MHz, the transformer shrinks but you need careful layout and snubbing. The 75% maximum duty cycle is a practical ceiling for flyback and forward converters — it limits the off-time available for resetting the transformer core, so the turns ratio and output voltage range are constrained accordingly. If you need higher duty cycle for a wide-input design, this part isn't the fit. ## Active status and sourcing posture It is ROHS3 compliant, so it passes EU and most global environmental requirements without an exemption.","metaTitle":"UCC28220D PWM Controller, 200kHz-2MHz, 75% Duty Cycle","metaDescription":"UCC28220D active PWM controller from TI.
