Description
General part information
LT1111 Series
The LT1111 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 2V to 12V in step-up mode and to 30V in step-down mode. The LT1111 functions equally well in step-up, step-down, or inverting applications.The LT1111 oscillator is set at 72kHz, optimizing the device to work with off-the-shelf surface mount inductors. The device can deliver 5V at 100mA 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 open-collector gain block can be configured as a low-battery detector, linear post regulator, undervoltage lock-out circuit, or error amplifier.For input sources of less than 2V use the LT1110.Applications3V to 5V, 5V to 12V Converters9V to 5V, 12V to 5V ConvertersRemote ControlsPeripherals and Add-On CardsBattery Backup SuppliesUninterruptible SuppliesLaptop and Palmtop ComputersCellular TelephonesPortable InstrumentsFlash Memory VPP Generators
