Comparator K7
K7 serves to recognize overcurrents. This is the reason why both inputs of the
operational amplifier have been brought out. Turning on is resumed after error recovery
at the beginning of the next half period but without using the soft start. K7 has a common-
mode input voltage range between 0 V and + 4 V. The delay time between occurrence
of an error and disabling of the outputs is only 250 ns.
Outputs
Both outputs are transistors with open collectors and operate in a push-pull
arrangement. They are actively low. The time in which only one of the two outputs is
conductive can be varied infinitely. The length of the falling edge at VCO is equal to the
minimum time during which both outputs are disabled simultaneously. The minimum
L voltage is 0.7 V.
Reference Voltage
The reference voltage source is a highly constant source with regard to its temperature
behavior. It can be utilized in the external wiring of the op amp, the error comparators,
the ramp generator, or other external components.
