LT1109 Overview
Key Features
- The LT1109-5 can deliver 5V at 100mA from a 3V input and the LT1109-12 can deliver 12V at 60mA from a 5V input
- The 8-pin versions also feature a logic controlled SHUTDOWN pin that turns off the oscillator when taken low
- The gated-oscillator design requires no frequency compensation components
- The high frequency 120kHz oscillator permits the use of small surface mount inductors and capacitors
- For a 5V to 12V at 120mA converter, see the LT1109A
- Foa a 5V to 12V at 200mA converter with 20µA shutdown current, see the LT1301
