Product data sheet
8.1 Start-up
When the applied voltage at V
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 (C
used for the floating supply of the high side driver.
During start-up, the voltage on the frequency capacitor (C
start-up state. The output voltage of the error amplifier is kept constant (typ. 2.5 V) and
switching starts at about 80 % of the maximum frequency at the moment pin V
the start level.
The start-up state is maintained until V
activated and the converter starts operating.
