The HHS60 Series converters do not require any
Figure 13. Output Current with Shorted Output Pins,
Vin = 48Vdc, Scale is 20Amp/Div.
Once the output current is brought back into its
specified range, the converter automatically exits the
hiccup mode and continues normal operation.
Overvoltage Protection
The output overvoltage protection consists of a
separate control loop, independent of the primary
control loop. This control loop has a higher voltage
set point than the primary loop. In a fault condition
the converter limits its output voltage and latches off.
Figure 14 shows operation of the converter under an
overvoltage condition.
external components for proper operation. However,
if the distribution of the input voltage to the converter
contains significant inductance, the capacitor C1
may be required to enhance performance of the
converter. A minimum of a 100 μ F electrolytic
capacitor with the ESR < 0.7 Ω is recommended for
the HHS60 series.
If the magnitude of the inrush current needs to be
limited, for suggestions see the “Inrush Current
Control Application Note” on the Power-One website
at www.power-one.com.
For output decoupling we recommend using one
10 μ F tantalum and one 1 μ F ceramic capacitors
connected directly across the output pins of the
converter. Note, that the capacitors do not substitute
the filtering required by the load.
Shutdown Feature Description
The ON/OFF (# 3) pin of the HHS60 Series
converters is referenced to the –Vin (# 1) pin (see
Figure 5). Both negative and positive logic models
are available.
With negative logic (which is denoted by the suffix “–
N” in the part number), when the ON/OFF pin is
pulled low, the unit is turned on.
With the positive logic, when the ON/OFF pin is
pulled low, the output is turned off and the unit goes
into a very low input power mode.
