8.2 Typical Application
The LMR16030 only requires a few external components to convert from wide voltage range supply to a fixed output voltage. A schematic of 5-V / 3-A application circuit is shown in Figure 8-1. The external components have to fulfill the needs of the application, but also the stability criteria of the control loop of the device.
