The ATX104plusHR is a 88 Watt high power DC/DC converter for PC/104+ systems. The supply provides +5 V, +3.3 V, +12 V, -12 V, and -5 V to the PC/104 bus and to the PC/104-Plus bus. Additionally, +5 V, +3.3 V, +12 V, and -12 V are provided at auxiliary connectors on the supply. The ATX104plusHR provides the additional ATX signals PS_ON#, PWR_ON and +5 VSB on the PCI bus using the reserved pins.
The design uses a +5 V dual phase supply cascaded to a +12 V and a -12 V circuit. The -5 V is cascaded from the -12V circuit. The +5V is designed for 50 Watts, the +1 2V is designed for 24 Watts, and the -12V is designed for 6 Watts.
The ATX104plusHR was designed to work without a heatsink and is easily integrated into IDAN systems using conduction cooling.
