Technical  
Specification  
IQ24xxxSMXxxx  
Application Section  
OUTPUT VOLTAGE TRIM (Pin 6): The TRIM input permits the  
user to adjust the output voltage across the sense leads up or  
down according to the trim range specifications.  
PROTECTION FEATURES  
Input Under-Voltage Lockout: The converter is designed  
to turn off when the input voltage is too low, helping avoid an  
input system instability problem, described in more detail in  
the application note titled “Input System Instability” on our  
website. The lockout circuitry is a comparator with dc hysteresis.  
When the input voltage is rising, it must exceed the typical Turn-  
On Voltage Threshold value (listed on the specifications page)  
before the converter will turn on. Once the converter is on,  
the input voltage must fall below the typical Turn-Off Voltage  
Threshold value before the converter will turn off.  
To decrease the output voltage, the user should connect a  
resistor between Pin 6 and Pin 5 (SENSE(-) input). For a desired  
decrease of the nominal output voltage, the value of the resistor  
should be

Output Current Limit: The maximum current limit remains  
constant as the output voltage drops. However, once the  
impedance of the load across the output is small enough to make  
the output voltage drop below the specified Output DC Current-  
Limit Shutdown Voltage, the converter turns off.

To increase the output voltage, the user should connect a  
resistor between Pin 6 and Pin 7 (SENSE(+) input). For a desired  
increase of the nominal output voltage, the value of the resistor  
should be  
The converter then enters a “hiccup mode” where it repeatedly  
turns on and off at a 5 Hz (nominal) frequency with a 5% duty  
cycle until the short circuit condition is removed. This prevents  
excessive heating of the converter or the load board.

Output Over-Voltage Limit: If the voltage across the output  
pins exceeds the Output Over-Voltage Protection threshold, the  
converter will immediately stop switching. This prevents damage  
to the load circuit due to 1) excessive series resistance in output  
current path from converter output pins to sense point, 2) a  
release of a short-circuit condition, or 3) a release of a current  
limit condition. Load capacitance determines exactly how high  
the output voltage will rise in response to these conditions. After  
200 ms the converter will automatically restart.

Trim graphs show the relationship between the trim resistor  
value and Rtrim-up and Rtrim-down, showing the total range the  
output voltage can be trimmed up or down.  
Note: the TRIM feature does not affect the voltage at which the  
output over-voltage protection circuit is triggered. Trimming the  
output voltage too high may cause the over-voltage protection  
circuit to engage, particularly during transients.  
Over-Temperature Shutdown: A temperature sensor on  
the converter senses the average temperature of the module.  
The thermal shutdown circuit is designed to turn the converter  
off when the temperature at the sensed location reaches the  
Over-Temperature Shutdown value. It will allow the converter  
to turn on again when the temperature of the sensed location  
falls by the amount of the Over-Temperature Shutdown Restart  
Hysteresis value.  
It is not necessary for the user to add capacitance at the  
Trim pin. The node is internally bypassed to eliminate noise.  
* For 1.2Vout unit replace 1.225 with 0.6 (see Trim Up  
Graph Common Figure 3).  
Total DC Variation of VOUT: For the converter to meet its  
full specifications, the maximum variation of the dc value of  
VOUT, due to both trimming and remote load voltage drops,  
should not be greater than that specified for the output  
voltage trim range.
