Typical System Application (TTL shutdown function)

Logic level signals shutdown function can be used in typical system application with external

components. When the TTL high voltage above 3.3V(referenced to ground, lower than VIN), the

converter will shutdown, input current less than 5mA; when the TTL Low voltage below

0.8V(referenced to ground), the converter will turn on.
