DESCRIPTION\nThe LT1110 is a versatile micropower DC-DC converter. The device requires only three external components to deliver a fixed output of 5V or 12V. The very low minimum supply voltage of 1.0V allows the use of the LT1110 in applications where the primary power source is a single cell. An on-chip auxiliary gain block can function as a low battery detector or linear post regulator.\nThe 70kHz oscillator allows the use of surface mount inductors and capacitors in many applications. Quiescent current is just 300μA, making the device ideal in remote or battery powered applications where current consumption must be kept to a minimum.\nThe device can easily be configured as a step-up or step-down converter, although for most step-down applications or input sources greater than 3V, the LT1111 is recommended. Switch current limiting is user-adjustable by adding a single external resistor. Unique reverse battery protection circuitry limits reverse current to safe, non-destructive levels at reverse supply voltages up to 1.6V.FEATURES\n■ Operates at Supply Voltages From 1.0V to 30V\n■ Works in Step-Up or Step-Down Mode\n■ Only Three External Off-the-Shelf Components Required\n■ Low-Battery Detector Comparator On-Chip\n■ User-Adjustable Current Limit\n■ Internal 1A Power Switch\n■ Fixed or Adjustable Output Voltage Versions\n■ Space-Saving 8-Pin MiniDIP or S8 PackageAPPLICATIONS\n■ Pagers\n■ Cameras\n■ Single-Cell to 5V Converters\n■ Battery Backup Supplies\n■ Laptop and Palmtop Computers\n■ Cellular Telephones\n■ Portable Instruments\n■ Laser Diode Drivers\n■ Hand-Held Inventory Computers
