pecification
Start Sync (pin B): The Start Synchronization pin will allow
a more consistent start-up sequence. To operate this feature,
connect together the Start-Sync pins of multiple current-sharing
units. This will permit immediate start-up with loads greater
than the current limit of a single unit. Without this connection,
any set of converters attempting to asynchronously start (or re-
start) with a load greater than the current limit of a single unit
will "hiccup". This “hiccup” mode will continue until one con-
verter attempts a start at the same time as the minimum num-
ber of additional units necessary to sustain the load condition.
For example, three 50 amp units starting into a 90 amp load
would require two units to simultaneously attempt a start. The
Start Sync connection synchronizes these starting attempts
and provides a more consistent and reliable start-up
sequence. For details about the "hiccup mode" or repeated
startup attempts, please see the "Startup Inhibit Period" note
in this Technical Specification.
Clock Sync (pin A): The External Clock Synchronization pin
provides the ability for the user to control the EMI signature and
synchronize sensitive circuitry to quiet periods in the converter
operation. With this option, the converter can be synchro-
nized to an external clock signal whose frequency is greater
than that of the free-running internal clock. However, substan-
tially raising the converter’s frequency will reduce its efficien-
cy. Therefore, the recommended frequency range for the exter-
nal clock synchronization signal applied to this pin would be
the lowest value possible without dropping below the mini-
mum frequency listed below:
340 KHz for the 26V unit
The following requirements should also be met:
The external clock signal should be referenced to the
negative input voltage, Vin(-).
The high level of the signal should be between 3.5V
and 5.0V.
The low level should be between -0.5V and +1.2V.
Do not apply a clock signal lower than the specified
frequency.
RoHS Compliance: The EU led RoHS (Restriction of Hazardous
Substances) Directive bans the use of Lead, Cadmium,
Hexavalent Chromium, Mercury, Polybrominated Biphenyls
(PBB), and Polybrominated Diphenyl Ether (PBDE) in Electrical
and Electronic Equipment. This SynQor product is available as
5/6 RoHS compliant (product with lead) or 6/6 RoHS compliant.
For more information please refer to SynQor’s RoHS addendum
available at our RoHS Compliance / Lead Free Initiative web
page or e-mail us at rohs@synqor.com.
