25V, 2A(IOUT), 2.2MHz Step-Down DC/DC Converter with Linear Controller in 3mm x 3mm DFN

Linear Technology announces the LT1939, a 2A, 25V step-down switching regulator and a linear controller in a 3mm x 3mm DFN package. The LT1939 operates from a VIN range of 3V to 25V, making it suitable for regulating power from a wide variety of sources, including protected automotive batteries, industrial supplies and unregulated wall adapters. Its 2.3A internal switch can deliver up to 2A of continuous output current at voltages as low as 0.8V. Switching frequency is user programmable and synchronizable from 250kHz to 2.2MHz, enabling designers to optimize efficiency while avoiding critical noise-sensitive frequency bands.
