The LT3494AEDDB#PBF is a micropower low-noise Boost Converter with integrated power switch, Schottky diode and an 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 current limit for the LT3494A respectively. The quiescent current is a low 65µA, which is further reduced to less than 1µA in shutdown. 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.
● Switching frequency is non-audible over entire load range
● Integrated Schottky diode
● Integrated output disconnect
● Integrated output dimming
