Figure 14 shows the mono mode output power as a function of power supply voltages for

loads of 2, 3, and

Ω Ohms. The same current limits as those given for Figure 13 apply,

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.

Figure 15 shows the output power as a function of power supply voltages for loads of 4, 6,

and 8

Ω when the STA323W is operated in a half-bridge binary mode. The solid curves

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.
