Product Overview

The LT1108CS8-5#PBF is a versatile micropower DC/DC Converter requires only four 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 LT1108 functions equally well in step-up, step-down or inverting applications. The LT1108 is pin-for-pin compatible with the LT1173, but has a duty cycle of 70%, resulting in increased output current in many applications. It can deliver 150mA at 5V from a 2 AA cell input and 5V at 300mA from 9V in step-down mode. Quiescent current is just 110µA, making the LT1108 ideal for power conscious battery operated systems. 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 lockout circuit or error amplifier.
  • Works in step-up or step-down mode
  • Only three external components required
  • Low-battery detector comparator on-chip
  • User adjustable current limit
