The LT1109A is a simple step-up DC/DC converter. The 8-
pin DIP or SOIC devices require only four external compo-
nents to construct a complete DC/DC converter. Current
drain is just 360
μ
A at no load, making the device ideal for
cost-sensitive applications where standby current must
be kept to a minimum.
The LT1109A-12 can deliver 12V at over 150mA from a 5V
supply, enough power to program four flash memory
chips simultaneously. The LT1109A-5 can deliver 5V at up
to 110mA from a 2V input. The devices feature a shutdown
pin that turns off the oscillator when taken low. The gated-
oscillator design requires no frequency compensation
components. High frequency 120kHz operation permits
the use of small surface mount inductors and capacitors.
