The UCC280x-Q1 family of high-speed, low-power integrated circuits contain all of the control and drive components required for off-line and DC-to-DC fixed frequency current-mode switching mode power supplies with minimal parts count.

These devices have the same pin configuration as the UCx84x family, and also offer the added features of internal full-cycle soft start and internal leading-edge blanking of the current-sense input.

The UCC280x-Q1 family offers a variety of package options, temperature range options, choice of maximum duty cycle, and choice of critical voltage levels. Lower reference parts such as the UCC2803-Q1 and UCC2805-Q1 fit best into battery-operated systems, while the higher reference and higher UVLO hysteresis of the UCC2802-Q1 and UCC2804-Q1 make these ideal choices for use in off-line power supplies.

The UCC280x-Q1 series is specified for operation from –40°C to 125°C.

参考设计

PMP23061 — 适用于牵引逆变器应用的预调节隔离式驱动器辅助电源参考设计

这款前置稳压、隔离式开环 LLC 变压器驱动器转换器参考设计可为牵引逆变器应用提供总功率高达 6W 的四路 18V 输出。LLC 拓扑使变压器具有较大的漏电感和超小的初级至次级电容，从而大大减少了通过偏置变压器注入的共模电流。升压前置稳压器旨在为 LLC 转换器提供 7.5W 功率，最高可支持 6W 输出功率。
