PPT-Buck Regulator Architectures

44 Constant On Time COT Buck Regulators Constant ONTime COT Hysteretic Regulator Advantages Constant frequency vs V IN High Efficiency at light load Fast transient response Disadvantages. The regulator features an active low delayed reset output flag which can be used to reset a microprocessor system on turnON and in the event that the regulator output falls out of regulation for any reason An external capacitor programs a delay time have more than one output as shown in Figure 1 separate filter inductors L1L2 are normally used in each output These independent inductors hurt performance by decoupling and isolating the outputs from each other Dynamic cross regulation is very poor lapis. , William?.

The idea of a multi-phase buck regulator is to put several buck regulators in parallel but have them operate in an interleaving manner. See figure below. The three-phase synchronous buck regulator has identical components for each phase, but the switching actions are 120 degrees out of phase..
