Output Filtering
The Micro TLynx
ripple voltage and will meet the maximum output ripple
specification with 0.1 µF ceramic and 10 µF ceramic
capacitors at the output of the module. However,
additional output filtering may be required by the system
designer for a number of reasons. First, there may be a
need to further reduce the output ripple and noise of the
module. Second, the dynamic response characteristics
may need to be customized to a particular load step
change.
To reduce the output ripple and improve the dynamic
response to a step load change, additional capacitance
at the output can be used. Low ESR ceramic and
polymer capacitors are recommended to improve the
dynamic response of the module. Figure 36 provides
output ripple information for different external
capacitance values at various Vo and for load currents
of 12A while maintaining an input voltage of 5V. Fig 37
shows the performance with a 3.3V input. For stable
operation of the module, limit the capacitance to less
than the maximum output capacitance as specified in
the electrical specification table. Optimal performance
of the module can be achieved by using the Tunable
Loop

Safety Considerations
For safety agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards,
i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE
0850:2001-12 (EN60950-1) Licensed.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power
module has extra-low voltage (ELV) outputs when all
inputs are ELV.
Feature Descriptions
Remote On/Off
The Micro TLynx
remote On/Off operation. Two On/Off logic options are
available. In the Positive Logic On/Off option, (device
code suffix “4” – see Ordering Information), the module
turns ON during a logic High on the On/Off pin and turns
OFF during a logic Low. With the Negative Logic
On/Off option, (no device code suffix, see Ordering
Information), the module turns OFF during logic High
and ON during logic Low. The On/Off signal is always
referenced to ground. For either On/Off logic option,
leaving the On/Off pin disconnected will turn the module
ON when input voltage is present.
For positive logic modules, the circuit configuration for
using the On/Off pin is shown in Figure 38. For positive
logic modules, the circuit configuration for using the
On/Off pin is shown in Figure 38. When the external
transistor Q1 is in the OFF state, Q2 is ON, the internal
PWM Enable signal is pulled low and the module is ON.
When transistor Q1 is turned ON, the On/Off pin is
