Defaults:Ambient temperature TA = 25oC. 40W
power transistor with TJMAX = 225oC, cooled by‘top
hat' heat sink with θCA = 5oC/W.

An ideal class-B amplifier is required for a RL = 5Ω load.

(a) Using the default power transistors, determine the minimum supply rail voltage required if TJ < 105oC is required.

(b) If the supply rail voltage VS = (+-) 12V what is the minimum allowed load resistance RL and maximum power that these transistors (as
constrained) can deliver to the load?
