Linear Technology announces the LT3495/-1 low noise boost converters with integrated power switches, Schottky diodes and output disconnect circuitry. The LT3495 uses a 650mA switch whereas the LT3495-1 uses a 350mA switch. Both parts are packaged in a 2mm x 3mm DFN-10 package. Their wide 2.3V to 16V input voltage range enables them to operate from single cell Li-Ion batteries up to fixed 12V input rails, delivering outputs up to 40V. The LT3495 can deliver over 70mA of output current at 16V from a single Li-Ion cell, making it ideal for applications such as OLED displays.
