ABOUT THE IDDV-6304140A
The highly efficient, high-performance 140-watt IDDV-6304140A
DC-to-DC vehicle ATX converter module provides 5V, 3.3V, 12V,
-12V and 5VSB outputs. The IDDV-6304140A is designed for vehicle
PC and receives a wide range of inputs between 6 and 30 VDC. The
IDDV-6304140A is built on an intelligent design and provides
outstanding line and load regulations. The IDDV-6304140A is
capable of sustaining 90% power efficiency.
The power module also solves the 5V standby problem by cutting off
the 5VSB rail after an amount of time (defined by jumper settings) to
prevent the battery from draining. When the battery voltage is below
10.7V for more than thirty seconds, the IDDV-6304140A shuts down.
The IDDV-6304140A reactivates again only when the input voltage
is higher than 10.7V.
