Multiple-Ouput 25W DC/DC Converter For Use In Vehicles

A versatile unit that can be supplied +5V, outputs only or can include features such as Power Management, Universal Battery Charger, AC Bus termination, +12V output, -5V output, -12V output and custom output voltages from –42V to +42V, the V104 has heavy-duty transient suppressors (5000W) that clamp the input voltage to safe levels, while maintaining normal power operation.

Battery, DC and AC input configurations from 8 to 30V are all handled by the V104 automatically. The V104 is a ‘simple switcher’ based design that provides outstanding line and load regulation with efficiencies up to 80 percent. Organic semiconductor capacitors provide filtering that reduces ripple noises below 30mV. The low noise design makes the V104 ideal for applications wherever EMI or RFI must be minimized.

The +5VDC and +12VDC outputs are controlled by a constant off-time current-mode architecture regulator, which provides excellent line and load transient response. The +12VDC boost regulator uses the +5VDC as input power and therefore can operate without dropout from 8 to 30V input and supply 1A.

The Power Management controller (PM104) allows timed on/off control of the V104, bus interrupts on impending power failure, current limit setting and intelligent charge termination for the UBC104. The V104 is provided in a PC/104 form factor compliant size, which includes the 8bit and 16bit PC/104 expansion bus header.

The V104 is part of a range of PC/104 power supplies from DSL which extends to a 108 watt power supply with a 6V to 40V DC input range and +3.3V, +5V, +12V, -12C DC output.
