Linear Technology is offering a MP-grade version of the LTC3412A, which 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 ideal 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.

The LTC3412AMP is ideal for high reliability applications that can experience a very wide ambient temperature range.

The LTC3412AMPFE is available in a TSSOP-16E package.
