* Nominal = DAC setpoint voltage with no adaptive output voltage positioning.
Note:
Adaptive Transient Voltage Output
In order to improve transient response a
40mV offset is built into the Current Sense
comparator. At high currents, the peak
output voltage will be lower than the
nominal set point , as shown in Figure 1.
The actual output voltage will be a function
of the sense resistor, output current and
output ripple.
Time - 100µs/Div.
