Product Overview

The LT1107IS8#PBF is a versatile micropower DC-to-DC Converter for use with LCD bias generators. 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 LT1107 functions equally well in step-up, step-down or inverting applications. The LT1107 is pin-for-pin compatible with the LT1111, but has a duty cycle of 70%, resulting in increased output current in many applications. The LT1107 can deliver 150mA at 5V from a 2AA cell input and 5V at 300mA from 24V in step-down mode. Quiescent current is just 320µA, making the LT1107 ideal for power-conscious battery-operated systems. The 63kHz oscillator is optimized to work with surface mount inductors and capacitors. 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, undervoltage lock-out circuit or error amplifier.
