Description

The ATX35104 is an 88 Watt high power DC/DC converter in a PCIe/104 format. The supply provides +5V, +3.3V, and +12V to the PCIe/104 bus. Additionally, +5V, +3.3V, and +12V, and -12V are provided at auxiliary connectors on the supply. The ATX35104 provides the additional ATX signals PS_ON#, PWRGOOD and +5VSB on the PCIe bus using the reserved pins and PCI-Express dedicated pins. Contact RTD Tech Support about configuring your RTD Single Board Computer for use with this feature.

The design uses a +5V dual phase supply cascaded to a +12V and a -12V circuit. The +5V is designed for 50 Watts, the +12V is designed for 24 Watts, and the -12V is designed for 6 Watts.

The ATX35104 was designed to work without a heat sink and is easily integrated into IDAN systems using conduction cooling.
