Product Overview


The LT1931ES5#PBF is an industry's highest power inverting SOT-23 current mode DC/DC Converter includes a 1A integrated switch allowing high current outputs to be generated in a small footprint. The LT1931 switches at 1.2MHz. 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. Easy pin-for-pin upgrades for higher power LT1611 applications. The LT1931 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.
  • Fixed frequency 1.2/2.2MHz operation
  • 1mVP-P Output ripple very low noise
  • Uses small surface mount components
  • <1µA Low shutdown current
  • 400mV at 1A Low VCESAT switch
  • Pin-for-pin compatible with the LT1611
