output voltage improves efficiency, but as output voltage drops below the circuit ' s 8V bootstrap voltage, IC 1dissipates additional power and requires caution to avoid exceeding its ratings. Figure 2shows The circuit ' s measured efficiency versus output current for three input voltages.One practical application for the circuit met a customer's requirement for A/DC converter that would operate from a 24V Source and deliver 12V output at currents as high as 3A. This routine-sounding specificat
