Figure 7. Mono Bridge Output, DDX^® Mode Only, Power vs Supply <1% THD.
Figure 7 depicts the mono mode output power as a function of power supply voltages for loads of 2, 3,
and 4 Ohms. The same current limit observations from Figure 6 apply, except output current is 7A
minimum, 12A typical in mono bridge configuration. Solid curves depict typical performance and dotted
curves depict the minimum current limit for the DDX-2102. Again, the output power curves assume
proper thermal management of the power device’s internal dissipation.
NOTE: Output power at 10% THD is approximately 30% higher.
Specifications are subject to change without notice.
