Product Overview

The LT1073CN8-5#PBF is a versatile micropower DC/DC Converter requires only three external components to deliver a fixed output of 5 or 12V. The very low minimum supply voltage of 1V allows the use of the LT1073 in applications where the primary power source is a single cell. An on-chip auxiliary gain block can function as a low-battery detector or linear post-regulator. Average current drain is just 135µA unloaded, making it ideal for applications where long battery life is important. The circuit shown can deliver 5V at 40mA from an input as low as 1.25 and 5V at 10mA from a 1V input. The device can easily be configured as a step-up or step-down converter. Switch current limiting is user-adjustable by adding a single external resistor. Unique reverse-battery protection circuitry limits reverse current to safe, non-destructive levels at reverse supply voltages up to 1.6V.
