The LT3494EDDB#TRPBF from Analog Devices is a micropower, low noise boost converter designed for applications requiring efficient power conversion with minimal audio band noise. It features integrated power switch, Schottky diode, and output disconnect circuitry. The device utilizes a novel control technique to maintain high efficiency across a wide load current range while ensuring the switching frequency remains above the audio band.
Key electrical specifications include a wide input voltage range of 2.3V to 16V and an adjustable output voltage capability up to 40V. The integrated NPN power switch has a current limit of 115mA. It boasts low quiescent current, drawing only 65μA in active mode and less than 1μA in shutdown mode. The internal disconnect circuitry isolates the output from the input during shutdown.
This boost converter is available in a tiny 8-lead 3mm x 2mm DFN package, making it suitable for space-constrained designs. Its low noise characteristics and integrated features make it ideal for applications such as OLED power supplies from single Li-Ion cells, low noise power applications, and portable electronics like MP3 players.
