Introduction

The 820153 DC-DC Power Supply is a fully compliant ATX power supply designed to power a wide variety of
motherboards like the KT690mITX, 786LCD/mITX, 886LCD-M and 986LCD-M families of boards. It has
included cable kit inclusive ATX+12V cable, as required by the 986LCD-M family, and it is supporting a wid er
temperature range than the standard embedded PC range 0 - 60ºC.

The 820153 comes with complete cable harness consisting of:

Note 1: Used for battery driven application. Not needed for standard ATX PSU mode.

The power supply can be operated in two types of modes: “Standard ATX Supply Mode” and “Battery Driven
Application Mode”. The input power voltage shall be 10 – 25V except for Battery Driven Application Mode
where the minimum power input voltage is 11.2V (down to 8V is allowed for maximum 1 minute). The power
input is protected against over-voltage transients, short circuits (>15A) and in Battery Driven Application Mode
the battery is protected against Deep Discharging.

In order to estimate if the DC-DC Power Supply is suitable for a specific project the following table can be
used.

The allowed load (without forced air) can be compared to the maximum load of the actual board. Maximum
load from LCD, HDD, PCI, AGP cards must be taken into consideration to make sure none of the outputs is
overloaded. The “green” numbers are the available power for these loads.
