Tiny 5-Lead SOT-23 Package

The LT

1611 is the industry’s first inverting 5-lead SOT-23

current mode DC/DC converter. Intended for use in small,

low power applications, it operates from an input voltage

as low as 1.1V and switches at 1.4MHz, allowing the use

of tiny, low cost capacitors and inductors 2mm or less in

height. Its small size and high switching frequency enable

the complete DC/DC converter function to consume less

than 0.25 square inches of PC board area. Capable of

generating – 5V at 150mA from a 5V supply or – 5V at

100mA from a 3V supply, the LT1611 replaces nonregulated

“charge pump” solutions in many applications.

The LT1611 operates in a dual inductor inverting topology

which filters the input side as well as the output side of the

DC/DC converter. Fixed frequency switching ensures a

clean output free from low frequency noise typically present

with charge pump solutions. No load quiescent current of

the LT1611 is 3mA, while in shutdown quiescent current

drops to 0.5µA. The 36V switch allows V

to V

OUT

differential of up to 33V.

The LT1611 is available in the 5-lead SOT-23 package.
