汽车用混合式集成电路调节器的发展过程中,随着输出级功率管饱和电压降的下降和反向击穿电压的增加,为了经受温度周期变化,因此进一步提高单块集成电路抗脉冲的能力以及厚膜电路式样的改进,已成为设计的重要课题。大功率复合管已具有150V以上的反向击穿电压与较大的二次击穿能力以及小于1.2V的饱和电压降。具有小的饱和电压降和能承受大于
In the development of automotive hybrid IC regulators, with the decrease of the saturation voltage drop and the reverse breakdown voltage of the power stage in the output stage, in order to withstand the temperature cycling, the capability of anti-pulse of the monolithic IC is further improved As well as thick film circuit design improvements, has become an important issue of design. High-power composite pipe has a reverse breakdown voltage of 150V or more and a large secondary breakdown ability and a saturation voltage drop of less than 1.2V. Has a small saturation voltage drop and can withstand greater than
