Design & Feature Considerations
Maximum Capacitive Load
The DCW1000 series has limitation of maximum
connected capacitance at the output. The power
module may be operated in current limiting mode
during start-up, affecting the ramp-up and the startup
time.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as
practicable across the load will give the best ripple and
noise performance.
To reduce output ripple, it is recommended to use
3.3uF capacitors at the output.

Remote On/Off
The DCW1000 has nagetive remote on/off logic.
Negative logic remote on/off turns the module on during
a logic low voltage on the remote on/off pin, and off
during a logic high.
Remote on/off can be controlled by an external switch
between the on/off terminal and the -Vin terminal. The
switch can be an open collector or equivalent.

Overcurrent Protection
To provide protection in a fault (output overload) condition,
the unit is equipped with internal current limiting circuitry
and can endure current limiting for an unlimited duration.
At the point of current-limit inception, the unit shifts from
voltage control to current control. The unit operates
normally once the output current is brought back into its
specified range.
Soldering and Cleaning Considerations
Post solder cleaning is usually the final board assembly
process before the board or system undergoes electrical
testing. Inadequate cleaning and/or drying may lower the
reliability of a power module and severely affect the
finished circuit board assembly test. Adequate cleaning
and/or drying is especially important for un-encapsulated
and/or open frame type power modules. For assistance
on appropriate soldering and cleaning procedures,
please contact Delta’s technical support team.
Notes:
1. These power converters require a minimum output load
to maintain specified regulation (please see page 6 for
the suggested minimum load). Operation under no-load
conditions will not damage these modules; however,
they may not meet all specifications listed above.
2. These DC/DC converters should be externally fused at
the front end for protection.
