Non-isolated

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!
