Description:

Micropower DC/DC Converter

Features

* s Operates at Supply Voltages from 2V to 30V s Works with Surface Mount Inductors s 72kHz Oscillator s Only Three External Components Required s Step-Up or Step-Down Mode s Low-Battery Detector Comparator On-Chip s User Adjustable Current Limit s Internal 1A Power Switch s Fixed or Adjustable Output

Applications

* The LT1111 oscillator is set at 72kHz, optimizing the device to work with off-the-shelf surface mount inductors. The device can deliver 5V at 100mA from a 3V input in step-up mode or 5V at 200mA from a 12V input in stepdown mode. Switch current limit can be programmed with a single resistor. An aux
