For the MAPC-104-5V model version, spare +5 Vdc power may be taken
from the P2 connector which is adjacent to the pin 1 end of the J1 connector
(see drawings). Be aware that this power is generated on the MAPC-104
and therefore is in addition to whatever 5V current is used by the host PC-
104 system. All power characteristics (regulation, tempco, ripple, etc.) are
derived from the MAPC-104.

The contacts are rated at 5 Amps 250Vac. However, whatever current is drawn must be
summed
with current powering the PC-104 system.

➀
All models are tested and specified with a single, external, 0.1µF, multi-layer ceramic output
capacitor on each output and no external input capacitors, unless otherwise noted. All models
will effectively regulate under no-load conditions (with perhaps a slight increase in output
ripple/noise).
➁
See Technical Notes/Performance Curves for additional explanations and details.
➂
Input Ripple Current is tested/specified over a 5-20MHz bandwidth with an external 33µF input
capacitor and a simulated source impedance of 220µF and 12µH. See I/O Filtering, Input Ripple
Current and Output Noise for details.
➃
The Current-Limit-Inception point is the output current level at which the converter's power-
limiting circuitry drops the output voltage 3% from its initial value. See Output Current Limiting
and Short-Circuit Protection for more details.
➄
See Dynamic Load Response for detailed results including switching frequencies.
➅
For Start-Up-Time specifications, output settling time is defined as the output voltage having
reached ±1% of its final value and the load current having reached at least 80% of its
final value.
➆
MTBF is calculated using TELCORDIA SR-332 Method 1 Case 3, ground fixed, +25°C ambient
air and full-load conditions. Contact DATEL for demonstrated life test data.
➇
All models are fully operational and meet all published specifications, including "cold start,"
at –40°C.
➈
The highly unlikely, simultaneous failure of several specific on-board components could
result in the MAPC-104's input voltage appearing at its output, despite the unit's output
overvoltage protection mechanisms. In this rare situation, the Power Good signal
(IPH pin 2, Pwr_LED_Drive) will be deactivated and systems monitoring Power Good will
eventually shut down. If you are using an MAPC-104 to power a load that must be protected
against any and all possible overvoltages, no matter how rare, you will have to provide
the protection external to the MAPC-104. Please contact DATEL for recommendations.

Connector Designations
The official PC/104 bus specification identifies the standard interboard bus
connections as paired J1/P1 and J2/P2 on one side and J3/P3 on the other
side. However, J1/P1/J2/P2 is physically all one big 4-row connector with J1/
J2 bus receptacle sockets (female) on the top side and P1/P2 pins (male) on
the bottom. This arrangement provides interboard pass-through connections
between PC/104 boards. DATEL refers to this single connector as “J1.”
DATEL’s auxiliary connectors (the IPH and the 5V Auxilliary Power Connec-
tor) are internally designated P1 and P2 respectively and this nomenclature
may appear on the board silkscreening. This is purely an artifact of auto-
mated sequential part numbering in our CAD system and has no relation to
the standard PC/104 interboard bus connectors. Don’t get the connectors
confused since they are all very different types and locations!

Self-Protection Features
The MAPC-104 contains two systems for protection of out-of-limit voltages,
currents and temperature. These systems control two output lines located on
the Input Power Header connector. Both systems operate independently and
concurrently. The MAPC-104 will respond to both temperature and voltage/
current simultaneously.
The output circuits for both these controls are shown below. Both of them will
drive either an external LED lamp and/or a logic circuit. The Overtemperature
Warning Circuit assumes that an external pullup resistor is supplied by the
user. The Power Good Circuit (“Pwr_LED_Drive Out”) includes an on-board
pullup resistor to drive an external LED with about 15mA.
Pwr_LED_Drive Out (pin 2, pullup to internal +5V):
HI (transistor off) = Power is normal. LED lamp is illuminated.
LO (transistor on) = Power fault, LED lamp is dark
Overtemperature Operation
The overtemperature system includes a on-board temperature sensor, a local
microcontroller with A/D inputs, a timer and hysteresis so that the user may
take steps to prevent inadvertant shut down. Operation proceeds as follows:
If the on-board temperature exceeds +115°C, the OT_Warn Output is
asserted (LO) by the microcontroller and an internal 30 second software
timer is started. The outputs remain powered on.
If the 30-second timer has not expired and the on-board temperature cools
below +110°C, the OT_Warn Output will be deasserted (HI) and operation
will continue unchanged.
½½½½½½½½½½
½½½½½½½½
½½½½½½
½½½½½½½
½½½½½½½½½½½
½
If the 30-second timer has expired and the temperature still exceeds +115°C,
the outputs will shut down. As soon as the on-board temperature cools to
less than +110°C, the MAPC-104 will automatically restart and power will be
restored to the outputs.
The 5 degree hysteresis between 110 and 115°C prevents rapid cycling of
the OT_Warn Output.
If the on-board temperature reaches +125°C, the outputs will shut down,
regardless of the state of the 30-second timer. The temperature must cool to
less than +110°C for autorestart.

The transistors in these outputs are either on (typically less than 0.4 Volts
out) or off (high impedance state). Depending on how the user wires the
external circuit, these indicators have the following sense:
OT_Warn Out (pin 1):
HI (transistor off) = temperature is normal
LO (transistor on) = Over temperature condition
