LINEAR TECHNOLOGY - LT1109A handbook

Update: 30 September, 2023

The LT1109A is a micropower DC/DC converter that can be used as a flash memory VPP generator. It supports 5V and 12V fixed outputs, or an adjustable version. The device uses off-the-shelf inductors, is low cost, and only requires an 8-pin DIP or SOIC package. The no-load current is only 360µA, making it ideal for cost-sensitive applications where standby current must be kept to a minimum. The LT1109A-12 can provide over 150mA of 12V power from a 5V supply, enough to program four flash memory chips simultaneously. The LT1109A-5 can provide up to 110mA of 5V power from a 2V input. The device has a shutdown pin that turns off the oscillator when the pin is low. The gated-oscillator design requires no frequency compensation components. High frequency 120kHz operation permits the use of small surface mount inductors and capacitors.
