DESIGN & FEATURE CONSIDERATONS
Remote On/Off
Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin, and off during a logic low. To turn the
power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the -Vin terminal. The
switch can be an open collector or equivalent.
A logic low is -0.7V to 0.8V.
A logic high is 2.5V to 5.5V.
The maximum sink current at on/off terminal during a logic low is -1mA. The maximum allowable leakage current of the switch at on/off
terminal (2.5 to 5.5V) is 50uA.
Over Current Protection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure current
limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit
operates normally once the output current is brought back into its specified range.
