Operating information continued
Parallel Operation
Two converters may be paralleled for redundancy if external
o-ring diodes are used in series with the output. It is not
recommended to parallel the converters without using
external current sharing circuits.
Remote Sense
The DC/DC converters have remote sense that can be used
to compensate for moderate amounts of resistance in the
distribution system and allow for voltage regulation at the
load or other selected point. The remote sense lines will carry
very little current and do not need a large cross sectional
area. However, the sense lines on PCB should be located
close to a ground trace or ground plane. In a discrete wiring
situation, the use of twisted pair wires or other technique to
reduce noise susceptibility is highly recommended. The
remote sense circuitry will compensate for up to 10% voltage
drop between the sense voltage and the voltage at the output
pins. The output voltage and the remote sense voltage offset
must be less than the minimum over voltage trip point. If the
remote sense is not needed the —Sense should be connected
to —Out and +Sense should be connected to +Out.
Over Temperature Protection (OTP)
The converters are protected from thermal overload by an
internal over temperature shutdown circuit. When the PCB
temperature close to the PWM control circuit exceeds 130C
the converter will shut down immediately. The converter will
restart when the temperature drops below 120C.
Over Voltage Protection (OVP)
The converters have output over voltage protection that will
shut down the converter in over voltage conditions. The
converter will make continuous attempts to start up (non-
latching mode) and resume normal operation automatically
after removal of the over voltage condition.
Over Current Protection (OCP)
The converters include current limiting circuitry for protection
at continuous overload.
The output voltage will decrease towards zero for output
currents in excess of max output current (max IO). The
converter will resume normal operation after removal of the
overload. The load distribution should be designed for the
maximum output short circuit current specified.
Input and Output Impedance
The impedance of both the input source and the load will
interact with the impedance of the DC/DC converter. It is
important that the input source has low characteristic
impedance. The converters are designed for stable operation
without external capacitors connected to the input or output.
The performance in some applications can be enhanced by
addition of external capacitance as described under External
Decoupling Capacitors. If the input voltage source contains
significant inductance, the addition of a 100 F capacitor
across the input of the converter will ensure stable operation.
The capacitor is not required when powering the DC/DC
converter from an input source with an inductance below
10 H.
Thermal Consideration
General
The converters are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
Cooling is achieved mainly by conduction, from the pins to
the host board, and convection, which is dependant on the
airflow across the converter. Increased airflow enhances the
cooling of the converter.
The Output Current Derating graph found in the Output
section for each model provides the available output current
vs. ambient air temperature and air velocity at Vin = 53 V.
The DC/DC converter is tested on a 254 x 254 mm,
35 m (1 oz), 8-layer test board mounted vertically in a wind
tunnel with a cross-section of 305 x 305 mm.
Proper cooling of the DC/DC converter can be verified by
measuring the temperature at positions P1. The temperature
at this position should not exceed the max values provided in
the table below.
Note that the max value is the absolute maximum rating
(non destruction) and that the electrical Output data is
guaranteed up to Tref +90°C.
See Design Note 019 for further information.
