Part Number: UCC28C56L Other Parts Discussed in Thread: TL431 , 反激电源产生4路+15V,为三相电机半桥驱动电路的3路上桥臂和3路下桥臂共6个IGBT门极供电,反馈环路选择副边TL431+光耦的方案。请问应该选择上桥臂还是下桥臂的门极电源作为反馈环路的检测源?选择上、下桥臂的优缺点分别是什么?

请问下ZKA在手册上电气化特性中的测试条件是VKA = Vref, f ≤ 1 kHz, IKA = 1 mA to 100 mA,手册上最严苛的测试条件是IKA的中心值是1mA,电流波动幅度是多大呢?如果幅度是1mA那么IKA<Imin了,不能正常工作?
请问手册上具体测试条件是什么?IKA中心值是(1mA+100mA)/2=50.5mA吗?

Hello Team,
My customer is asking What difference between TL431QDBZR and TL431QDBZR series shunt regulator, we can find similar performance 431 with different prefix.
What's different between those series shunt regulator?
How customer…
