默认转换以相同的Junction为目标,因此状态机将在On状态或ReadyForOn状态下启动,具体取决于模拟启动时Ierr是否大于0。 图2:使用状态机的恒定接通时间控制器 使用标准控制块的COT实现如PLECS演示模型库中的演示模型“串联电容器降压转换器Series Capacitor Buck Converter”所示。 3 Simulation 运行模拟以查看输出电压、电感...
A constant ON-time controller for a buck converter utilizes dual symmetrical ramps. The ramps may be generated artificially or by sensing the voltage across a sense resistor in the output. The ramp may also be generated by sensing the voltage across the "ON" resistance of the low side FET ...
Figure 3shows a low-cost buck-boost converter based on the LM5010 buck-regulator IC that converts a 10 to 50V positive supply voltage into –12V. Although many applications use a fixed switching frequency and modulate the output pulse width, this design features a constant-on-time approach in...
