output voltages with external 1x10 F, 1x47 F,

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.
The input to these units is to be provided with a fast-
acting fuse with a maximum rating of 6A in the
positive input lead.
Feature Descriptions
Remote Enable
The 12V Pico TLynx
TM 6A power modules feature an
On/Off pin for 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 42. When
the external transistor Q1 is in the OFF state, the
internal PWM Enable signal is pulled high through an
internal 1.5M
Ω resistor and the external pullup
resistor and the module is ON. When transistor Q1 is
turned ON, the On/Off pin is pulled low and the
module is OFF. A suggested value for Rpullup is 20k
Ω.

Figure 42. Circuit configuration for using positive
On/Off logic.
For negative logic On/Off modules, the circuit
configuration is shown in Fig. 43. The On/Off pin
should be pulled high with an external pull-up resistor
(suggested value for the 4.5V to 14V input range is
20Kohms). When transistor Q2 is in the OFF state,
the On/Off pin is pulled high, transistor Q1 is turned
ON and the module is OFF. To turn the module ON,
Q2 is turned ON pulling the On/Off pin low, turning
transistor Q1 OFF resulting in the PWM Enable pin
going high.
