DESCRIPTION
The LT1109A is a simple step-up DC/DC converter. The 8-pin DIP or SOIC devices require only four external components to construct a complete DC/DC converter. Current drain is just 360µA at no load, making the device ideal for cost-sensitive applications where standby current must be kept to a minimum.
