External loop compensation is required for converter stability, and is formed by
connecting a compensation resistor-capacitor series-network (
BUC and GND.
In the case of overload or short-circuit at
overcurrent threshold
overcurrent comparator immediately. The pulse width is then controlled by the
overcurrent comparator as seen before in the boost description.
In order to protect the
an overvoltage protection is provided which switches the output transistor off as soon as
the voltage at pin
6.0 V.
