The UCC28070-Q1 is an advanced power factor correction (PFC) controller that integrates two pulse-width modulators (PWMs) operating interleaved by 180° in CCM boost-mode. Derived from the UCC28070, this device can switch at frequencies from 30kHz up to 300kHz. The 180° out-of-phase interleaved operation results in substantial reduction of high-frequency input and output ripple currents and conducted-EMI filtering becomes easier and less expensive. The UCC28070-Q1 features multiple innovations including current synthesis and quantized voltage feedforward to promote performance enhancements in PF, efficiency, THD, and transient response. In addition, frequency dithering, clock synchronization, and slew-rate enhancement further expand the potential for performance improvements. Also, protection features include output overvoltage detection, programmable peak-current limit, undervoltage lockout, and open-loop protection.
