Adding a dual USB switch
(MAX1558) to a switching regulator
(MAX5035B) yields a small circuit
that can be built into the plug of an
automotive cigarette lighter. It
enables the single lighter socket to
power or charge two automotive
accessories such as portable
navigation devices, while providing
fault indicators and overload protection.
Automotive accessories such as portable navigation devices (PNDs) are usually
powered or charged using a simple adaptor plugged into the cigarette lighter. But,

what if you want to power or charge two devices at once? The circuit in Figure
1 is just what you need.
Figure 1. This automotive USB power supply generates two regulated, supply-voltage
outputs from a single unregulated input.
IC1 generates 5V from any input between and 76V. That range is wide
enough to include plete range of car-battery voltage plus the 40V spike
that can occur during
