DESIGN CONSIDERATIONS
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.
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
maximum 10A time-delay fuse in the ungrounded lead.
Remote On/Off
The IPM series power modules have an On/Off control
pin for output voltage remote On/Off operation. The
On/Off pin is an open collector/drain logic input signal
that is referenced to ground. When On/Off control pin is
not used, leave the pin unconnected.
The remote on/off pin is internally connected to +Vin
through an internal pull-up resistor. Figure 29 shows the
circuit configuration for applying the remote on/off pin.
The module will execute a soft start ON when the
transistor Q1 is in the off state.
The typical rise for this remote on/off pin at the output
voltage of 2.5V and 5.0V are shown in Figure 17 and 18.

FEATURES DESCRIPTIONS
Over-Current Protection
To provide protection in an output over load fault
condition, the unit is equipped with internal over-current
protection.
triggered, the unit enters hiccup mode. The units
operate normally once the fault condition is removed.
Pre-Bias Startup Capability
The IPM would perform the monotonic startup into the
pre-bias loads; so as to avoid a system voltage drop
occur upon application. In complex digital systems an
external voltage can sometimes be presented at the
output of the module during power on. This voltage may
be feedback through a multi-supply logic component,
such as FPGA or ASIC. Another way might be via a
clamp diode as part of a power up sequencing
implementation.
Output Voltage Programming
The output voltage of IPM can be programmed to any
voltage between 0.8Vdc and 5Vdc by connecting one
resistor (shown as Rtrim in Figure 30, 31) between the
TRIM and GND pins of the module to trim up (0.9V ~ 5V)
and between the Trim and +Output to trim down (0.8V ~
0.9V). Without this external resistor, the output voltage of
the module is 0.9 Vdc. To calculate the value of the
resistor Rtrim for a particular output voltage Vo, please
use the following equation:
