ESCRIPTION
The output is electronically protected against no-load, overload and short circuit. In case of an overload or
short circuit, the device will operate intermittently (hiccup mode).
The device can supply resistive and inductive loads.
Avoid loads with large input capacitances. If the capacitive load is higher than the values specified, the device
operates in an intermittent mode (hiccup mode).

The output voltage can be adjusted with an external resistor connected between the TRIM-pin and the output
voltage.
The device is equipped with sense lines for the output voltage. This feature moves the output voltage
regulation point from the output of the device to the point of connection of the remote sense pins.
The device is equipped with an over-temperature protection. In case of a high temperature, the output shuts
down and starts automatically after cooling off.
The device is equipped with under-voltage protection on the input side. If the input voltage is too low, the
device does not start or switches off. The turn-on and shut-down voltage can be adjusted externally.
In case of an internal defect, a redundant circuit prevents the output voltage from becoming excessive or
dangerous (zener diode type protection).
The device is equipped with a remote ON/OFF function.
The device has an access to the internal bus voltage, which can be used to add additional components for
extended hold-up time.
The device is equipped with a SYNC control pin for frequency synchronization with an external clock signal.
All parameters are typical values specified at nominal input voltage, nominal output load, 25°C ambient and after a 5 minutes run-in time unless
otherwise noted. The information presented in this document is believed to be accurate and reliable and may change without notice.
