Analog Devices DC2914A Demo Boards offer three versions to show the three different staged start topologies of LTC4238. The LTC4238 Hot Swap Controllers allow a board to be safely inserted and extracted from a live backplane. The demo boards are created for 12V, 24V, and 48V systems and come loaded with advanced features incorporating SOA timer, COMM pin for scalability, and assorted operating modes.
The three variants of the boards include the DC2914A-A, DC2914A-B, and DC2914A-C. The DC2914A-A exhibits the parallel mode of operation for a 48V, 1.5kW application. The DC2914A-B shows the low stress staged start mode for a 48V, 2.5kW regulated input application. Furthermore, the DC2914A-C showcases the high stress staged start mode with SOA timer for 48V, 2.5kW application with large input steps.
The demo boards provide onboard LEDs that show the presence of input, output, power good signalling, and any fault if present. Long-term product reliability is accomplished by observing the high voltage layout rules.
