TYPICAL CHARACTERISTIC CURVES
7.1
This series of converters does not require any external components for proper operation. However, if the distribution of the
input voltage to the converter contains significant inductance, a capacitor across the input terminals may be required to
stabilize the input voltage. A minimum of 0.47μF, quality electrolytic or ceramic capacitor, is recommended for this purpose.
For output decoupling it is recommended to connect, directly across the output pins, a 0.47
μF
ceramic capacitor (for 3.3 V
and 5 V outputs) or a 0.27
μF
ceramic capacitor (for other outputs). Care must be taken to ensure the maximum rated output
capacitance for the device is not exceeded, when dimensioning decoupling capacitors in the system, as this could cause
the unit to detect an overload and enter a ‘hiccup’ mode of operation.
7.2
When the output is overloaded above the maximum output current rating, the voltage will start to reduce to maintain the
output power to a safe level. In a condition of high overload or short-circuit where the output voltage is pulled below
approximately 30% of Vo.nom, the unit will enter a ‘Hiccup’ mode of operation. Under this condition the unit will attempt to
restart, approximately every 100 ms until the overload has cleared.
7.3
Paralleling of two converters is possible by direct connection of the output voltage terminal pins. The load regulation
characteristic is designed to facilitate current sharing (typically ± 20%). However, this may cause start-up problems at initial
start-up, and is only recommended in applications where one converter is able to deliver the full load current (true redundant
systems).
7.4
The outputs of two units may be connected in series to achieve a higher system voltage.
