The LT1173CN8#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 range from 2 to 12V in step-up mode and to 30V in step-down mode. The LT1173 functions equally well in step-up, step-down or inverting applications. The LT1173 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.
● Works in step-up or step-down mode
● Only three external components required
● Low battery detector comparator on-chip
● User-adjustable current limit
● Fixed or adjustable output voltage versions
● Internal 1A power switch
