Error flag is an open collector output, when the regulated output voltage is lower than 5% of the rated output voltage (typical), it will send a signal. Initially, the error flag is low until the output voltage Voltage stabilizer reaches 95% of the rated output voltage is reached. In some cases, an error flag appears in the power converter there is a delay. This delay is set by an external capacitor, and can be used as power-reset function to reset the microprocessor to power up. If the display state "error", the output voltage is lower case such that the open collector output is high (Circuit breaker ). When the output voltage is within 5% of rated voltage up and down, this flag output is low.
Switch
"On / Off" or "stop" feature allows the regulator to be able to open or close the case charged. While in "off" or "stop" mode, the regulator supply current because the output is disabled and fell to a lower level, but the internal bias circuitry is still running. By re-enabled when the regulator will shut down than the input Air circuit breaker voltage and opened the case again much faster output voltage regulation. If the display in the "on" state, the logic high voltage regulator is started. Otherwise, a logic low will be started.
