The LT1931AES5#TRMPBF is a 2.2MHz inverting DC/DC Converter with an internal 1A switch allowing high current outputs to be generated in a small footprint. The LT1931A switches at 2.2MHz. This high speed enables the use of tiny, low cost capacitors and inductors 2mm or less in height. 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 LT1931A operates 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 2.2MHz operation
● Very low noise (1mVP-P output ripple)
● Uses small surface mount components
● Low shutdown current (<1µA)
● Low VCESAT switch (400mV at 1A)
● Pin-for-pin compatible with the LT1611
