ZHCSMO2A June 2022 – November 2022 LMR51430
PRODUCTION DATA
The LMR51430 only requires a few external components to convert from a wide voltage range supply to a fixed output voltage. Figure 9-1 shows a basic schematic.
The external components have to fulfill the needs of the application and the stability criteria of the control loop of the device. Table 9-1 can be used to simplify the output filter component selection.
