Injector Driver Module

[Lawrence King]

Hmmm... Why go to all of the trouble to switch the injectors from
+14V. This would be a very tricky switch mode power supply design. Why
not simply lower the drive voltage. If you drive the injectors from a
lower voltage (say +5V) then your power dissipation will drop to a
mangeable level.

National Semiconductor builds chips which are switch mode power
supplies (I think the family is called "simple-switcher") or you can
buy a commercial module (try PowerTrends http://www.powertrends.com/ )
to drop the voltage. This also solves the problem of not having enough
volts to fire the injectors while cranking.
