Linear Technology has announced the -55°C to 125°C grade (MP-grade) version of the LTC3414 in a plastic TSSOP-20 package. The LTC3414 is a high efficiency, 4MHz synchronous buck regulator using a constant frequency, current mode architecture. It can deliver up to 4A of continuous output current at voltages as low as 0.8V. It operates from an input voltage 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 operates over a -55°C to 125°C operating junction temperature range and is guaranteed and tested across the full temperature range. The feedback voltage specification is slightly derated (±0.5%), but the remainder of the electrical specifications are identical to the E and I grades. They are ideal for military and aerospace applications which are subjected to extreme ambient temperatures.

The LTC3414MPFE is available in a TSSOP-20 package.
