Functional description
7.1 Start-up
switch is turned-on while the high side power switch remains in the non-conducting state.
This start-up output state guarantees the initial charging of the bootstrap capacitor (Cboot)
used for the oating supply of the high side driver.
During start-up, the voltage on the frequency capacitor (Cf) is zero and denes the
start-up state. The voltage at the soft start pin (CSS) is set to 2.7 V. The CSS pin voltage
is copied to the VCO pin via a buffer and switching starts at about 80 % of the maximum
frequency at the moment VDD reaches the start level.
The start-up state is maintained until VDD reaches the start level (13.5 V), the oscillator is
activated and the converter starts operating.
