Demonstration circuit DC883 features the LT®3473 micropower step-up DC/DC converters with integrated Schottky diode and output disconnect circuitry. The output on DC883 is 25V at up to 80mA from a 3~4.2V input, while automatic Burst Mode operation maintains efficiency at light load. The lithium ion battery input voltage range, high output voltage, internal NPN power switch, minimal external components and simple design make the LT3473 an excellent solution for OLED and CCD Bias.
