In the practical Fly-Buck design, only the first stability criterion is critical and some margin should be given. When designing a Fly-Buck, start from some initial values for the ripple injection network, check the above three inequalities, and then adjust and iterate the circuit parameters accordingly.
In the next part, we will present a step-by-step guide about implementing these in the Fly-Buck design. Any questions so far? Site Search User. Share Contact author Subscribe by email More Cancel.

From a practical standpoint, the power supply designer needs to take many aspects into consideration, and adjustments may be required based on the board test result. These design steps are a good start to creating a LM Fly-Buck design. A quick start calculator for the LM Fly-Buck can be found here.
Various aspects of the design, including the associated practical problems and the proposed solutions, are detailed. A simple and easy-to-follow design procedure is also described. Experimental results are presented to illustrate the design procedure.
