DESIGN GUIDE
Output Connections and Considerations
The permissible load current must never be exceeded during
normal, abnormal or test conditions. Converters subject to dynamic
loading exceeding 25% of rated current must be reviewed by
Vicor Applications Engineering to ensure that the converter will
operate properly.
Under dynamic-load, light-load or no-load conditions, the converter
may emit audible noise. Converters that utilize remote sense may
require compensation circuitry to offset the phase lag caused
by the external output leads and load impedance. If an external
remote-sense circuit is used, the remote-sense leads must be
protected for conditions such as lead reversal, noise pickup, open
circuit or excessive output lead resistance between the sense
point and the converters output terminals. For applications that
may draw more than the rated current, a fast acting electronic
circuit breaker must be utilized to protect the converter. Under
no circumstance should the rated current be exceeded. Utilizing
or testing of current limit or short circuit current will damage the
converter. Ensure that the total output capacitance connected to
the converter does not exceed the limits on Page 16, “Maximum
Output Capacitance”, of the design guide.

24V Input
Module Enable/Disable
The module may be disabled by pulling PC to 0V (2.3V max) with
respect to the –Input. This may be done with an open collector
transistor, relay, or optocoupler. Converters may be disabled with a
single transistor or relay either directly or via “OR’ing” diodes for 2
or more converters. See Figure 2.
Primary Auxiliary Supply
During normal operation only, the PC Pin can source 5.7V
@ 1.5mA. In the example shown in Figure 4, PC powers a
module enabled LED.
Module Alarm
The module contains “watchdog” circuitry which monitors input
voltage, operating temperature and internal operating parameters.
In the event that any of these parameters are outside of their
allowable operating range, the module will shut down and PC will
go low. PC will periodically go high and the module will check to
see if the fault (as an example, Input Undervoltage) has cleared.
If the fault has not been cleared, PC will go low again and the
cycle will restart. The SC pin will go low in the event of a fault
and return to its normal state after the fault has been cleared. See
Figures 3 and 5.

Output Voltage Programming
The output voltage of the converter can be adjusted or
programmed via fixed resistors, potentiometers or voltage
DACs. See Figure 8.
Trim Down
1. This converter is not a constant-power device – it has a
constant current limit. Hence, available output power is
reduced by the same percentage that output voltage is
trimmed down. Do not exceed maximum rated output current.
2. The trim-down resistor must be connected between the SC
and –S pins. Do not bypass the SC pin directly with a capacitor.
Trim Up
1. The converter is rated for a maximum delivered power. To
ensure that maximum rated power is not exceeded, reduce
maximum output current by the same percentage increase in
output voltage.
2. The trim-up resistor must be connected between the SC and
+S pins. Do not bypass the SC pin directly with a capacitor.
3. Do not trim the converter above maximum trim range (typically
+10%) or the output over voltage protection circuitry may
be activated.
Parallel Bus – PR Pin
Parallel Operation
The PR pin supports paralleling for increased power with N+1
(N+M) redundancy. Modules of the same input voltage, output
voltage, and power level will current share if all PR pins are
suitably interfaced.
Compatible interface architectures include the following:
AC-coupled single-wire interface. All PR pins are connected to a
single communication bus through 0.001µF (500V) capacitors. This
interface supports current sharing and is fault tolerant except for
the communication bus. Up to three converters may be paralleled
by this method. See Figure 9.
Transformer-coupled interface. For paralleling four or more
converters a transformer-coupled interface is required, and under
certain conditions a PR buffer circuit.
For details on parallel operation please refer to the
Design Guide & Applications Manual for Maxi, Mini, Micro Family.

• The +OUT and –OUT
power buses should be
designed to minimize
and balance parasitic
impedance from each
module output to the
load.
• At the discretion of the
power system designer,
a subset of all modules
within an array may be
configured as slaves by
connecting SC
to –OUT.
• Do not use output
OR’ing diodes with
MicroMods.
• This module is designed for point-of-load regulation, where remote sensing is
not required. Active voltage drop compensator, as shown here, may be used
in applications with significant distribution losses.
Please consult with the Micro Family Isolated Remote Sense Application Note
for additional information.
