LT3494EDDB#TRMPBF

LT3494 is a low noise boost converter 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 internal disconnect circuitry allows the output voltage to be isolated from the input during shutdown. An auxiliary reference input (CTRL pin) overrides the internal 1.225V feedback reference with any lower value allowing full control of the output voltage during operation. It is widely used in application such as OLED power, low noise power, MP3 players etc.
