Product Overview

LT1173 is a versatile micropower DC-DC converter. This device functions equally well in step-up, stepdown or inverting applications. It consumes just 110µA supply current at standby, making it ideal for applications where low quiescent current is important. The device can deliver 5V at 80mA 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 gain block can be configured as a low battery detector, linear post regulator, under voltage lockout circuit or error amplifier. It is widely used in application such as flash memory Vpp generators, 3V to 5V, 5V to 12V converters, 9V to 5V, 12V to 5V converters, LCD bias generators, peripherals and add-on cards, battery backup supplies, laptop and palmtop computers, cellular telephones, portable instruments etc.
  • Operates at supply voltages from 2V to 30V
  • Works in step-up or step-down mode
  • Only three external components required
  • Low battery detector comparator on-chip
  • User-adjustable current limit
  • Internal 1A power switch
  • Fixed or adjustable output voltage versions
  • Oscillator frequency is 23KHz typical
