DCDC18R Boost Regulator
2
This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the
interference at his own expense.
*
The slow start boost regulator typically starts to work at a supply voltage of
about 10 volts. Supply voltages below 10 volts pass directly to V out (through
2 Schottky diodes dropping the voltage by ~ 0.6 volts). With the DCDC18R
operating at the maximum output current (18 V * 1 A = 18 W) the input power
required is up to 18 W / 0.8 efficiency = 22.5 watts; that is the maximum
current specification of 2.25 Amps at 10 volts.
