The UCC28070A device is an extended-frequency-range derivative of the UCC28070 device, capable of operating at low switching frequencies desired for IGBT power-switch based PFC converters in high-power applications.

The UCC28070A device is capable of operating at frequencies from 10kHz to 300kHz, thus extending the range of operation compared to the UCC28070 device whose minimum operating frequency was limited to 30kHz. All the other features and benefits of the UCC28070 device are also available in the UCC28070A device. The 180° out-of-phase interleaved operation generates substantial reduction in input and output ripple currents and conducted EMI filtering becomes easier and less expensive.

Like the UCC28070 device, the UCC28070A device also features multiple innovations including current synthesis and quantized voltage feedforward to promote performance enhancements in PF, efficiency, THD, and transient response. Features including frequency dithering, clock synchronization, and slew rate enhancement further expand the potential performance enhancements. All protection features in the UCC28070 device such as output overvoltage detection, programmable peak-current limit, undervoltage lockout, and open-loop protection are available in the UCC28070A device as well.
