ucc2803-q1
- qualified for automotive applications
- aec-q100 qualified with the following results:
- device temperature grade 1: –40°c to 125°c ta
- device hbm classification level 2: ±2 kv
- device cdm classification level c5: >1000 v
- 100-µa typical starting supply current
- 500-µa typical operating supply current
- operation up to 1 mhz
- internal soft start
- internal fault soft start
- internal leading-edge blanking of the current sense signal
- 1-a totem-pole output
- 70-ns typical response from current-sense to gate drive output
- 1.5% tolerance voltage reference
- same pinout as uc3842 and uc3842a
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。
