Linear Technology has announced the high reliability, MP-grade version of
the LTC3412A. The LTC3412A is a 4MHz synchronous buck
regulator that uses a constant frequency, current mode architecture. It
can deliver up to 3A of continuous output current at voltages as low as
0.8V from a thermally enhanced TSSOP-16 package. It operates from an
input voltage range of 2.25V to 5.5V, making it suitable for both
single-cell Li-Ion, or NiMH applications, as well as more general
purpose fixed rail systems. The MP-grade version is guaranteed to
operate over a -55°C to 125°C junction temperature range.
