The high-speed, low-power integrated circuit contains all the control and driver components needed for off-line and DC-to-DC fixed-frequency current-mode switching power supplies for UCC2800/1/2/3/4/5 homes with minimal parts.
These devices feature the same pinout configuration as the UC2842/3/4/5 series, but also offer internal full-cycle soft-start and internally leading current-sense input blanking value-added capabilities.
This UCC2800/1/2/3/4/5 home offers a choice of maximum duty cycle and voltage level is essential. For example UCC2803 with UCC2805 reference parts are best used in battery-powered systems, while higher reference and UCC2802 with higher UVLO hysteresis UCC2804 are ideal for use in offline power supplies.

The UC1861 IC - The 1868 series is ideal for the control of zero-current and zero-voltage switching quasi-resonant converters. The difference between this is from the UVLO threshold and the output selection of members of the various combination device family results. In addition, a single-pulse steering logic configuration scheme is available for both time zero-current systems (UC1865 - 1868) or shutdown times (UC1861 - 1864) for zero-voltage switching applications |
