Internally, these ports differ slightly in their function.  
In use, a low on Enable 1 completely shuts down all  
circuits in the converter while a low on Enable 2  
shuts down the secondary side while altering the  
controller duty cycle to near zero. Externally, the  
use of either port is transparent save for minor  
differences in standby current. (See specification  
table).  
requires transition times less than 100 ns, maximum  
low level of +0.8 volts and a minimum high level of  
+2.0 volts. The sync output of another converter  
which has been designated as the master oscillator  
provides a convenient frequency source for this  
mode of operation. When external synchronization  
is not required, the sync in pin should be left open  
(unconnected) thereby permitting the converter to  
operate at its' own internally set frequency.  
Synchronization of Multiple Converters  
The sync output signal is a continuous pulse train  
set at 550 ±50 KHz, with a duty cycle of 15 ±5%.  
This signal is referenced to the input return and has  
been tailored to be compatible with the AFL sync  
input port. Transition times are less than 100 ns and  
the low level output impedance is less than 50  
ohms. This signal is active when the DC input  
voltage is within the specified operating range and  
the converter is not inhibited. This output has  
adequate drive reserve to synchronize at least five  
When operating multiple converters, system  
requirements often dictate operation of the  
converters at  
a
common frequency.  
To  
accommodate this requirement, the AFL series  
converters provide both a synchronization input and  
a synchronization output.  
The sync input port permits synchronization of an  
AFL converter to any compatible external frequency  
source operating between 500 and 700 KHz. This  
input signal should be referenced to the input return  
and have a 10% to 90% duty cycle. Compatibility  
additional converters.

Parallel Operation — Current and Stress Sharing  
permits equal sharing among the members of a set  
where total load current exceeds the capacity of an  
individual AFL. An important feature of the AFL  
series operating in the parallel mode is that in  
addition to sharing the current, the stress induced by  
Figure III. illustrates the preferred connection  
scheme for operation of a set of AFL converters with  
outputs operating in parallel. Use of this connection
