LINEAR TECHNOLOGY LT1073 Manual
Update: 28 September, 2023
The LT1073 is a versatile micropower DC/DC converter that only requires three external components to deliver a fixed output of 5V or 12V. With a minimum supply voltage of 1V, it can be used 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. The average current drain of the LT1073-5 used in the typical application circuit 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 1.25V and 5V at 10mA from a 1V input. The device can easily be configured as a step-up or step-down converter, although for most step-down applications or input sources greater than 3V, the LT1173 is recommended. Switch current limiting is user-adjustable by adding a single external resistor. Unique reverse-battery protection circuitry limits reverse current to safe, nondestructive levels at reverse supply voltages up to 1.6V.
