Protection and Control
Valid Input Voltage Range:
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:
(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.
For Positive logic, the ON/OFF pin is brought to greater
than 4.0 V with respect to the –INPUT pin. To request
the Positive logic version, add the suffix (P) to the
standard part number. The positive version has a built-
in pull up resistor of approximately 100 kΩ.
