LT3494/LT3494A Micropower Low Noise Boost Converters with Output Disconnect FEATURES ■ DESCRIPTION The LT®3494/LT3494A are low noise boost converters with integrated power switch, Schottky diode and output disconnect circuitry. The parts use a novel* control technique resulting in low output voltage ripple as well as high efficiency over a wide load current range. This technique guarantees that the switching frequency stays above the audio band for the entire load range. The parts feature a high performance NPN power switch with a 350mA and 180mA current limit for the LT3494A and LT3494 respectively. The quiescent current is a low 65μA, which is further reduced to less than 1μA in shutdown.
