EQW010-040 Series Power Modules

be taken to ensure that the maximum output power of  
the module remains at or below the maximum rated  
power (Maximum rated power = Vo,set x Io,max).  
Feature Description  
Remote On/Off  
Two remote on/off options are available. Positive logic  
turns the module on during a logic high voltage on the  
ON/OFF pin, and off during a logic low. Negative logic  
remote On/Off, device code suffix “1”, turns the  
module off during a logic high and on during a logic  
low.

Overtemperature Protection  
To turn the power module on and off, the user must  
supply a switch (open collector or equivalent) to  
control the voltage (Von/off) between the ON/OFF  
terminal and the VIN(-) terminal (see Figure 60). Logic  
low is 0V Von/off 1.2V. The maximum Ion/off during a  
logic low is 1mA, the switch should be maintain a  
logic low level whilst sinking this current.  
To provide protection under certain fault conditions,  
the unit is equipped with a thermal shutdown circuit.  
The unit will shutdown if the thermal reference point  
Tref (Figure 63), exceeds 125oC (typical), but the  
thermal shutdown is not intended as a guarantee that  
the unit will survive temperatures beyond its rating.  
The module can be restarted by cycling the dc input  
power for at least one second or by toggling the  
remote on/off signal for at least one second. If the  
auto-restart option (4) is ordered, the module will  
automatically restart upon cool-down to a safe  
temperature.  
During a logic high, the typical maximum Von/off  
generated by the module is 15V, and the maximum  
allowable leakage current at Von/off = 5V is 1μA.  
If not using the remote on/off feature:  
For positive logic, leave the ON/OFF pin open.  
For negative logic, short the ON/OFF pin to VIN(-).  
Remote Sense  
Output Overvoltage Protection  
The output over voltage protection scheme of the  
modules has an independent over voltage loop to  
prevent single point of failure. This protection feature  
latches in the event of over voltage across the output.  
Cycling the on/off pin or input voltage resets the  
latching protection feature. If the auto-restart option  
(4) is ordered, the module will automatically restart  
upon an internally programmed time elapsing.  
Remote sense minimizes the effects of distribution  
losses by regulating the voltage at the remote-sense  
connections (See Figure 61). The voltage between  
the remote-sense pins and the output terminals must  
not exceed the output voltage sense range given in  
the Feature Specifications table:  
[VO(+) – VO(–)] – [SENSE(+) – SENSE(–)] 0.5 V  
Although the output voltage can be increased by both  
the remote sense and by the trim, the maximum  
increase for the output voltage is not the sum of both.  
The maximum increase is the larger of either the  
remote sense or the trim.  
Overcurrent Protection  
To provide protection in a fault (output overload)  
condition, the unit is equipped with internal  
current-limiting circuitry and can endure current  
limiting continuously. At the point of current-limit  
inception, the unit enters hiccup mode. If the unit is  
not configured with auto–restart, then it will latch off  
The amount of power delivered by the module is  
defined as the voltage at the output terminals  
multiplied by the output current. When using remote  
sense and trim, the output voltage of the module can  
be increased, which at the same output current would  
increase the power output of the module. Care should
