A monolithic step-down regulator that withstands the rigors of automotive environments and consumes only 100μA of quiescent current is described.
Monolithic buck switching regulator
automotive power design
Automobile electronic systems place high demands on today’s DC/DC converters. They must be able to precisely regulate an output voltage in the face of wide temperature and input voltage ranges—including load dump transients in excess of 60V and cold crank voltage drops to 4V. The converter must also be able to minimize battery drain in always-on ...
