3.2. DC-DC Converter Performance Characteristics
The dc-dc converter utilizes a digital control loop architecture operating at 250 kHz. The complete converter is
comprised of the Si3460 controller and the external components in the Si3460-EVB schematics. The performance
specifications in Table 7 are typical for the Si3460-EVB reference design.
