Description

Return for input voltage source. Internally connected to pin 7.

Inhibit/Enable control input. The converter is ON (ENABLE) when the voltage applied to

this pin is lower than 0.8V. The converter is OFF (INHIBIT) when this pin is unconnected or

the input voltage is in the range of 1.2 to Vi.

Power Fail programmable input. If unconnected the Power Fail threshold voltage is 11V

with 1V hysteresis (factory setting).

DC input voltage. Recommended maximum voltage is 40V.

Reset output (active high). When the supply voltage +Vin and the regulated output voltage

+Vo1 are in the correct range this signal is generated after a delay time of 100ms typical.

Regulated +5.1V output voltage.

Return for output 1 current path. Internally connected to pin 1.

Regulated +12 or +15V output.

Regulated – 12 or – 15V output.

External adjustment for output voltages ±12 and ±15V.

Return for ±12 and ±15V output current path.
