Analog Feature Descriptions
Remote On/Off
The module can be turned ON and OFF either by
using the ON/OFF pin (Analog interface) or through
the PMBus interface (Digital). The module can be
configured in a number of ways through the PMBus
interface to react to the two ON/OFF inputs:
Module ON/OFF can be controlled only
through the analog interface (digital interface
ON/OFF commands are ignored)
Module ON/OFF can be controlled only
through the PMBus interface (analog
interface is ignored)
Module ON/OFF can be controlled by either
the analog or digital interface
The default state of the module (as shipped from the
factory) is to be controlled by the analog interface only.
If the digital interface is to be enabled, or the module is
to be controlled only through the digital interface, this
change must be made through the PMBus. These
changes can be made and written to non-volatile
memory on the module so that it is remembered for
subsequent use.
Analog On/Off
The 12A Digital Pico DLynx
TM 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 should be 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 39. When the
external transistor Q2 is in the OFF state, the internal
transistor Q1 is turned ON, and the internal PWM
#Enable signal is pulled low causing the module to be
ON. When transistor Q2 is turned ON, the On/Off pin is
pulled low and the module is OFF. A suggested value
for Rpullup is 20k
Ω.
For negative logic On/Off modules, the circuit
configuration is shown in Fig. 40. The On/Off pin
should be pulled high with an external pull-up resistor
(suggested value for the 3V 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.
Digital On/Off
Please see the Digital Feature Descriptions
section.

On/Off logic.

On/Off logic.
Monotonic Start-up and Shutdown
The module has monotonic start-up and shutdown
behavior for any combination of rated input voltage,
output current and operating temperature range.
Startup into Pre-biased Output
The module can start into a prebiased output as long
as the prebias voltage is 0.5V less than the set output
voltage.
Analog Output Voltage Programming
The output voltage of the module is programmable to
any voltage from 0.6dc to 5.5Vdc by connecting a
resistor between the Trim and SIG_GND pins of the
module. Certain restrictions apply on the output
voltage set point depending on the input voltage.
These are shown in the Output Voltage vs. Input
Voltage Set Point Area plot in Fig. 41. The Upper Limit
curve shows that for output voltages lower than 1V, the
input voltage must be lower than the maximum of
14.4V. The Lower Limit curve shows that for output
voltages higher than 0.6V, the input voltage needs to
