LT1931 - 1.2MHz/2.2MHz Inverting DC/DC Converters In ThinSOT

The LT1931 LT1931A are the industrys highest power inverting SOT-23 current mode DC/DC converters. Both parts include a 1A integrated Switch allowing high current outputs to be generated in a small footprint. The LT1931 switches at 1.2MHz while the LT1931A switches at 2.2MHz. These high speeds enable the use of tiny, low cost capacitors and inductors 2mm or less in height. The LT1931 is capable of generating 5V at 350mA or 12V at 150mA from a 5V supply, while the LT1931A CAN generate 5V at 300mA using significantly smaller inductors. Both parts are easy pin-for-pin upgrades for higher power LT1611 applications. The LT1931 LT1931A operate in a dual inductor inverting topology that Filters both the input side and output side current. Very low output voltage ripple approaching 1mVP-P CAN be achieved when ceramic output capacitors are used. Fixed frequency switching ensures a clean output free from low frequency noise typically present with Charge Pump solutions. The low impedance output remains within 1% of nominal during large load steps. The 36V Switch allows VIN to VOUT differential of up to 34V.
The LT1931 LT1931A are available in the 5-lead ThinSOT package.
