loads of 2, 3, and Ω Ohms. The same current limits as those given for
except output current is 8 A minimum, with 12 A typical in the mono-bridge configuration.
The solid curves show typical performance and dashed curves depict the minimum current
limit. The output power curves assume proper thermal management of the power device's
internal dissipation.

depict typical performance. Minimum current limit is not reached for these combinations of
voltage and load impedance. The output power curves assume proper thermal management
of the power device's internal dissipation.
