description

The LT1109 is a simple step-up DC/DC converter. 8-pin is available to be able to do so, 3-pin TO-92 (fixed output) or miniDIP packages, and the device requires only three external components to build a complete DC/DC converter. The current consumption is only 320#181; An ideal device for cost-sensitive applications where standby current must be kept to a minimum at no load. The LT1109-5 can provide 5V 3V input and the LT1109-12 can provide 12V at 100mA from 5V input at 60mA. The 8-pin version also has a logic control shutdown when the shutdown pin is low and the oscillator is turned off. The design of gated oscillators requires the absence of frequency compensation elements. High-frequency 120kHz oscillators that allow the use of small surface-mount inductors and capacitors. The 120 mAh converter is at 5V to 12V, and the LT1109A is seen. FOA a 5V to 12V 20μA shutdown current in a 200mA converter, see the LT1301.
