Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community UCC28070A SLUSAW0A – MARCH 2012 – REVISED MAY 2016 UCC28070A Extended Frequency Range (10 kHz to 300 kHz), Interleaving Continuous.

General Description

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 highpower applications.

The UCC28070A device is capable of operating at frequencies from 10 kHz to 300 kHz, thus extending the range of operation compared to the UCC28070 device whose minimum operating frequency was limited to 30 kHz.

All the other

Key Features

  • 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 d.
