Linear Technology announces the I-grade version of the LTC3414. 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 from a thermally enhanced TSSOP-20 package. It operates from an input voltage of 2.25V to 5.5V, making it ideal for both single cell Li-Ion or multi-cell NiMH applications, as well as more general purpose fixed rail systems. The I-grade version operates from a -40°C to +85°C junction temperature and is guaranteed and production tested across this entire temperature range. All electrical specifications are identical to that with the E grade version. These devices are ideal for automotive and industrial applications, which are subjected to high ambient temperatures.

The LTC3414IFE is available from stock in a TSSOP-20E package. Pricing starts at $5.45 each for 1,000-piece quantities.
