Protection and Control Valid Input Voltage Range: The converter measures the input voltage and will not allow operation outside of the input voltage specification. As shown by the graphs, hysteresis is added to both the high and low voltage to prevent the converter from turning on and off repeatedly when the voltage is held near either voltage extreme. At low line this assures the maximum input current is not exceeded; at high line this assures the semiconductor devices in the converter are not damaged by excessive voltage stress. ON/OFF Logic Option: The ON/OFF control logic can be either Negative (standard) or Positive to enable the converter. For Negative logic, the ON/OFF pin is brought below 1.0 V with respect to the –INPUT pin to enable the converter. The pull-down must be able to sink 100 µA. For Positive logic, the ON/OFF pin is brought to greater than 4.0 V with respect to the –INPUT and be limited to less than 10V. To request the Positive logic version, add the suffix (P) to the standard part number. The ON/ OFF pin has a built-in pull up resistor of approximately 100 k Ω to +5V. Application Notes |
