34V, 2A Output, 2.8MHz Step-Down DC/DC Converter MILPITAS, CA - March 14, 2007 - Linear Technology Corporation announces the LT3684, a 2A, 34V step-down switching regulator packaged in a 3mm x 3mm DFN or MSOP-10E. The LT3684 operates within a VIN range of 3.6V to 34V (36VMAX), making it ideal for load dump and cold-crank conditions found in automotive applications. Its 3.2A internal switch can deliver up to 2A of continuous output current at voltages as low as 1.265V. Switching frequency is user programmable from 300kHz to 2.8MHz, enabling the designer to optimize efficiency while avoiding critical noise-sensitive frequency bands. The combination of its 3mm x 3mm DFN-10 package (or thermally enhanced MSOP-10E) and high switching frequency, which keeps external capacitors and inductor small, provides a very compact, thermally efficient footprint. The LT3684 utilizes a high efficiency 3.2A, 0.18 Ohm switch, with the necessary boost diode, oscillator, control and logic circuitry integrated into a single die. Special design techniques enable high efficiency over a wide input voltage range while its current mode topology enables fast transient response and excellent loop stability. Other features include, a power good flag and soft-start capability. The LT3684EDD and LT3684EMSE pricing starts at $2.95 each for 1,000-piece quantities. The LT3684IDD and LT3684IMSE are tested and guaranteed to operate from a -40°C to 125°C operating junction temperature, are priced at $3.54 each. All versions are available from stock.
