The Harsh Reality of Wide-Ranging 4VвЂ“36V Automotive
Batteries Is No Problem for Triple Output Regulator in
4mmВ Г—В 5mm QFN
Michael Nootbaar DC/DC converters for automotive applications must operate
in an environment of extremes. Input transients can exceed
the nominal battery voltage by a factor of five and last
hundreds of milliseconds, while temperatures under the
hood soar far above the capability of typical commercial
grade ICs. In this harsh environment, space is tight, so even
the most robust devices must perform multiple functions.
The LT3694/LT3694-1 meets these requirements by combining a 2.6A switching
regulator and two low dropout linear
regulators in a compact 4mmВ Г—В 5mm
QFN package or a thermally enhanced
TSSOP. The switching regulator requires
a single inductor and has an internal
power switch, cycle-by-cycle current
limiting and track/soft-start control. Each
LDO requires only an external NPN pass
transistor and includes foldback current limiting and track/soft-start control. An internal overvoltage detector
shuts off the switching regulator when
VIN exceeds 38V, protecting the switch and
the Schottky rectifier. This allows it to …
