LвЂ‰DESIGN FEATURES Industrial/Automotive Step-Down
Regulator Accepts 3.6V to 36V
and Includes Power-On Reset and
Watchdog Timer in 3mm Г— 3mm QFN
by Ramanjot Singh Introduction
As the number of microprocessors in
automotive and industrial applications continues to expand, so does the
need for rugged step-down regulators
that can operate over a wide input
voltage range and withstand high
voltage transients and output shorts.
Microprocessor-based applications
also require supervisory functions,
such as power-on reset (POR) and
watchdog timing, to ensure high system reliability. The regulator must
have high efficiency at light loads
to increase battery life. The LT3689
delivers all of these features in tiny
16-pin 3mm Г— 3mm QFN and 16-pin
MSOP packages. Features of the LT3689
Step-Down Regulator The LT3689 employs a constant frequency, current mode architecture to
provide 800mA of continuous output
current. The part operates from a …
