Product Overview
The LT1111CN8#PBF is a versatile micropower DC-to-DC Converter for use with uninterruptible supplies. The device requires only three external components to deliver a fixed output of 5 or 12V. Supply voltage ranges from 2 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.
