  • Product introduction

The UCC35705 and UCC35706 devices are the primary end-controller for 8-pin voltage mode and fast overcurrent protection. These devices are part of the high-speed, high-performance, isolated and non-isolated power converters that serve as the core.

The UCC35705/UCC35706 devices feature a high-speed oscillator with integrated feed-forward compensation to improve converter performance. A fast response with a typical current-sense output delay of 25 ns provides overload conditions. The IC also provides an accurate added protection that can also be used for oscillators with disabilities operating in the maximum possible maximum possible duty cycle programmable duty cycle clamp.

Two UVLO options are available. The lower turn-on voltage for DC-DC converters is intentionally based on the UCC35705, while the higher on-voltage and undervoltage lockout range of the UCC35706 is ideal for better off-line applications.

UC3864 TI 08+ 16PDIP The IC-1868 series of UC1861 is best suited for the control of zero-current switching and zero-voltage switching quasi-resonant converters. This differs from UVLO's threshold and output selection to the members of the various combinations of device family results. In addition, a single-pulse steering logic configuration scheme is configured for either zero-current systems at the time (UC1865-1868) or zero-voltage switching applications at off-time (UC1861-1864).
