Description
General part information
LT1173 Series
The LT1173 is a versatile micropower DC-DC converter. The device requires only three external components to deliver a fixed output of 5V or 12V. Supply voltage ranges from 2.0V to 12V in step-up mode and to 30V in step-down mode. The LT1173 functions equally well in step-up, step-down or inverting applications.The LT1173 consumes just 110µA supply current at standby, making it ideal for applications where low quiescent current is important. The device can deliver 5V at 80mA from a 3V input in step-up mode or 5V at 200mA from a 12V input in step-down mode.Switch current limit can be programmed with a single resistor. An auxiliary gain block can be configured as a low battery detector, linear post regulator, under voltage lock-out circuit or error amplifier.For input sources of less than 2V, use the LT1073.ApplicationsFlash Memory Vpp Generators3V to 5V, 5V to 12V Converters9V to 5V, 12V to 5V ConvertersLCD Bias GeneratorsPeripherals and Add-On CardsBattery Backup SuppliesLaptop and Palmtop ComputersCellular TelephonesPortable Instruments
