DESIGN GUIDE – TPS43061 STEP-BY-STEP DESIGN PROCEDURE
The following section provides a step-by-step design guide of a high-frequency, high-power-density synchronous
boost converter with the TPS43061 controller combined with a NexFET™ power block. This design procedure is
also applicable to the TPS43060. A few parameters must be known in order to start the design process. These
requirements are typically determined at the system level. For this example, we will start with the following known
parameters.
