7.1
The oscillator turns on the power-switch with a constant frequency while the buck regulating circuit turns the
power-switch off in every cycle with an appropriate time gap depending on the output and input voltage.
The internal sawtooth signal used for the PWM generation has an amplitude proportional to the input supply
voltage (feedforward).
7.2
All parameters have been measured at 25°C, unless otherwise specified.
