Voltage regulator in Trucks

Voltage regulator in Trucks

Voltage regulator in Trucks

(OP)
Hello,

I'm an experienced designer in car body electronics. However, now, I've to design a body controller for a truck. My doubt is that I don't know which voltage regulator to use. I expect arround 150mA of current consumption which would give around 3watts of power dissipated in a linear voltage regulator at 24volts. In addition, I'm pretty sure that there's an even higher voltage battery specified for trucks.

In addition I need voltage regulator with low quiescent current.

Has anyone got experience using DC/DC converters in automotive? Any EMC issues?

Regards
Antonio

- "In addition, I'm pretty sure that there's an even higher voltage battery specified for trucks."

Unless your talking European , most American trucks are 12 or 24 Volts. The batterys are just in series, or series/parallel to acheve the quantity of current needed to turn over the engine. Average running system voltage is 14 / 28 volts.

Yes, what I meant is that nominal voltage is 24 volts but it is specified that it must work between 14 and 32 volts.

Thanks anyway!
