(10) Regulation specifications describe the deviation as the line input voltage or output load current is varied
(11) Other input or output voltage ranges will be reviewed under scheduled quantity special order.
(12) Maximum PC board temperature is measured with the sensor in the center of the converter.
(13) Do not exceed maximum power specifications when adjusting the output trim.
(14) The maximum output capacitive loads depend on the the Equivalent Series Resistance (ESR) of the external
(15) Do not allow the input voltage to degrade lower than the input undervoltage shutdown voltage at all times.
(16) The output is not intended to sink appreciable reverse current.
(17) “Hiccup” overcurrent operation repeatedly attempts to restart the converter with a brief, full-current output.

Rtrim resistor must be a 1/10 Watt precision metal fi lm type, ±1% accuracy

the resistor close to the converter with very short leads or use a surface
mount trim resistor.
the specifi ed limits of the output voltage or the converter’s maximum power
rating when applying these resistors. Also, avoid high noise at the Trim
input. However, to prevent instability, you should never connect any capaci-
tors to Trim.

Output noise may be further reduced by adding an external filter. At zero output current, the output may
contain low frequency components which exceed the ripple specification. The output may be operated
indefinitely with no load.

output capacitor and, to a lesser extent, the distance and series impedance to the load. Larger caps will
reduce output noise but may change the transient response. Newer ceramic caps with very low ESR may
require lower capacitor values to avoid instability. Thoroughly test your capacitors in the application. Please
refer to the Output Capacitive Load Application Note.
Otherwise, you risk having the converter turn off. The undervoltage shutdown is not latching and will
attempt to recover when the input is brought back into normal operating range.
If the overcurrent condition still exists, the restart current will be removed and then tried again. This short
current pulse prevents overheating and damaging the converter. Once the fault is removed, the converter
immediately recovers normal operation.
The On/Off Control Input should use either a switch or an open collector/open drain transistor referenced to
